In the last few posts of my blog I have been talking about the Museum’s holdings of hawkmoths, which amount to 289,000 specimens, and how the Lepidoptera section is dealing with the re-housing, care and accession of this important group.

 

This will be my last post related to this subject and in concluding I want to talk about a private collection of hawkmoths, specifically the Cadiou Collection, which has enriched and transformed the Museum lepidoptera holdings.

 

This large and valuable collection was purchased by the Natural History Museum in August 2008, thanks to the generous sponsorship of the Rothschild family, the de Rothschild family, the John Spedan Lewis foundation, Ernest Kleinwort Charitable Trust and members of the public.

 

Picture1edited.jpgThe Cadiou Collection with its 230,000 specimens was acquired for the nation and for science in August 2008.

 

 

PIc 2 J.M. Cadiou.jpg

Dr Jean-Marie Cadiou was a non-professional lepidopterist with an interest in hawkmoths.


 

Cadiou began amassing his collection while working for IBM in California in the late 1960s, and continued during his subsequent employment with NATO and the EU Directorates General. At the time of his unexpected and untimely death in May 2007, he had authored or co-authored 32 scientific papers and one book, described 65 species and subspecies of hawkmoths and managed to create an extensive collection of thousands of specimens.

 

Picture3.jpgFour hawkmoths described by Cadiou. From top left clockwise: Eupanacra busiris ssp. myosotis (Sulawesi), Orecta venedictoffae (Ecuador), Xylophanes haxairei (French Guiana, Colombia, Ecuador, north Brazil) and Rhodoprasina corrigenda (Thailand).

 

The Cadiou collection contained an estimated total of almost 230,000 pinned and papered specimens and when this collection was put on sale after Cadiou’s death the Museum couldn’t miss the chance to acquire it.

 

The reasons behind this interest were multiple:

  • The majority of the Cadiou material was post-1970 with precise locality data.
  • The collection contained at least one genus and 99 species and subspecies not represented in the Museum.
  • It was also rich in species of which the Museum had only five specimens or fewer (at least 200).

 

In comparison the Sphingidae collections of the Museum at that time comprised 60,000 pinned specimens, many of which were over 100 years old.

 

Pic4 Cadiou's mixed boxes.jpgTwo colleagues of mine went to Belgium to pick up the collection in Cadiou’s house. The plentiful and various types of boxes containing the specimens had to be packed into large cardboard boxes for ease of transport.

 

Copy of Picture5.jpg430 cardboard boxes containing the collection were loaded into a hired large track for transport.

 

Picture6.jpg

Meanwhile back in the UK a large freezer was hired to quarantine the material before transferring it into the collection areas.

 

Picture10.jpg

After 21 days in the freezer at -40°C, the boxes were finally moved in the collection area.

 

At that time the Lepidoptera collection was housed in one of the Museum's storage places in Wandsworth, while the new building that would have housed the entomology and part of the botany collections, namely the Darwin Centre, was being built in South Kensington.

 

Once in the collection, we started the process of transferring the pinned specimens from various kind of boxes and drawers of the Cadiou collection into refurbished Rothschild drawers. Many curators and a volunteer were involved in the transferring of the material, and eventually, just before the Lepidoptera collection was ready to join the other entomology collections in the newly built Darwin Centre, in South Kensington, all pinned specimens from the Cadiou collections were transferred into Rothschild drawers and ready to be moved in their new home.

At the end we had filled around 750 Rothschild drawers with pinned Sphingidae (top) and an extra 70 different types of drawers with non-sphingid Lepidoptera (bottom), all these from the Cadiou material.

 

We are now left with 120 boxes containing papered material, some of which has already been sent to Prague for mounting.

 

The actual amalgamation of all the Sphingidae in one large collection started in May 2010 and is still in progress. In this project I work alongside Ian Kitching, one of the researchers in our section and a world expert on Sphingidae. The aim of the project is to re-house the specimens from the main, supplementary, accession and the recently purchased Cadiou collections, into one collection inside refurbished Rothschild drawers.

 

Picture001.jpg

Some of the re-housed drawers of Sphingidae. From top left, clockwise: Langia zenzeroides ssp. formosana, Platysphinx stigmatica, Smerinthus ocellata ssp. atlanticus, Falcatula falcatus.

 

I am transferring the specimens using a relatively new way of arrangement which consists of rows of specimens facing each other. This method is particularly easy to carry out thanks to the falcate shapes of the dry pinned sphingids and has helped in increasing the number of specimens that fit in each drawer, therefore reducing the total number of drawers and ultimately the space necessary for their housing.

 

Pic11.jpg

By February 2014 I created 877 Rothschild drawers of hawkmoths from merging main, supplementary, accession and Cadiou collections. A total of approximately 45,000 specimens have been transferred so far. These include 105 genera out of a total of 207. The re-housed taxa have all been labelled and had their location, with other important details, recorded in our electronic database.

 

Picture13.jpg

Allow me to make a plea, before concluding. Of the 207 genera of Sphingidae so far known 206 are represented in our collections. The only one currently missing is the genus Baniwa which has only one species described in it, Baniwa yavitensis, from Venezuela. We really would like to have one!

 

However, this is not an invitation to collect it from the wild as this species is very rare and almost certainly protected. We certainly don’t endorse indiscriminate and illegal collecting, and specimens entering our collections need to be accompanied by a regular collecting permit. So, if there are some collections out there with surplus specimens of Baniwa, keen on giving one away (I can hear someone laughing mockingly), please get in touch. We shall provide it with a comfortable, and most of all protected, accommodation.

 

That’s it! I shall now officially relieve you from any further information about sphingids…well, only for a while though, because as you may have noticed, I have a soft spot for hawkmoths and can’t resist conversing regularly about them.

 

Thanks very much for following this blog trend on hawkmoths; I shall keep you posted with more news on lepidopterans and the Museum’s collections.

 

One last thing, don’t forget to visit our Sensational Butterfly exhibit, which opens on 3 April 2014. There are also some moths in the house and who knows, you might be lucky enough to be brushed past by a skilful and hurried flyer…did someone just mention a hawkmoth.

 

C. hylas edited.jpgI photographed this beautiful Cephonodes hylas resting and feeding on the flowers of the a Scarlet Milkweed (Asclepias curassavica) in a previous Butterfly Exhibit here at the Museum. Perhaps we'll be able to enjoy some nice hawkmoths this year too.

The re-housing of the Museum’s hawkmoths collection, one of my curatorial responsibilities, has been the subject of the last couple of posts. I talked about the transferring of specimens from outdated or transitory drawers into new, more permanent drawers, and of the amalgamation of the old Museum’s collections with newly acquired material, with particular reference to the collection of hawkmoths (Sphingidae).

 

I have also introduced some of the species from the Museum’s extended sphingid collection, consisting of around 289,000 specimens and, in this post, I would like to briefly tell of the history of the Museum's collection of hawkmoths. However, before I start delving into the past, I’d like to finish with the introduction of some of the species of hawkmoths I began in the previous post… so here are some other fascinating sphingids.

 

Cephonodes_hylas last edited.jpg

Some hawkmoths have a short and stout body, transparent wings, a distinct pattern and behaviour that make them look like bees or wasps.

 

This is Cephonodes hylas, a daily flying moth, widely distributed in Asia where it is often found in urban parks and gardens attracted by Gardenia, one of the caterpillar's food plants. When the adult moth emerges from the pupa, the wings are entirely covered with greyish scales. These come off in a little cloud after the first flight.

 

Hemaris fuciformis last edited.jpg

Another hymenoptera look alike is Hemaris fuciformis.

 

This little and pretty hawkmoth, with its plump body covered by yellowish and reddish hairs, and its transparent wings, looks very much like a bumble bee, and it flies rapidly like one too! This specie is widespread all over Europe eastward across northern Turkey, northern Afghanistan, southern Siberia, northern Amurskaya to Primorskiy Kray and Sakhalin Island. It has also been recorded from Tajikistan and northwest India.

 

Sataspes infernalis last edited.jpg

Sataspes infernalis is another daily flying hawkmoth that very convincingly mimics a carpenter bee.

 

Its wings are devoid of scales and are darker, more opaque and somehow iridescent compared to the previous two hawkmoths. This species is distributed in India, West China, Burma and Borneo.

 

Compsulyx last edited.jpg

Eye-spots are a common feature on the wings of Lepidoptera and hawkmoths are no exception. This stunning hawkmoth is Compsulyx cochereaui, an endemic species of New Caledonia.

 

Smerinthus ocellata last edited.jpg

Eye-spots are also found on the hind-wings of the species of hawkmoths belonging to the genus Smerinthus.

 

This genus includes 11 species and one of them is the eyed hawkmoth (Smerinthus ocellata). In the resting position the fore-wings cover the hind-wings with the eye spots, when the moth feels threatened, the fore-wings are suddenly pushed upward revealing the hind-wings decorated with intense blue and black 'eyes' on a pinkish and brown background.

 

The flashing of these false eye-spots may help in startling a potential predator giving the moth a chance to quickly fly away. The eyed hawkmoth is distributed across all of Europe (including the UK), through to Russia as far east as the Ob valley and to eastern Kazakhstan and the Altai. It has also been recorded in north and western China.

 

Pseudandriasa mutata last edited.jpg

Pseudandriasa mutata is a rather atypical sphingid

 

It doesn’t look particularly streamlined nor are its wings elongated like those of a typical hawkmoth. In fact when in 1855, Francis Walker - while studying specimens and describing new species from our Museum - came across a specimen of this hawkmoth, he recognized it as a new species but named it Lymantria mutata, thinking it belonged to the family of moths called Lymantriidae (Tussock moths).

 

Hayesiana triopus last edited.jpg

Hayesiana triopus is a lovely daily flying sphingid with translucent wings and a discontinuous pinkish-red belt and orange spots on a black abdomen.

 

The underside of the body, particularly of the thorax, abdomen and hind wings is reddish orange. This moth is a fast flyer but its rapid movements seem rather clumsy and, apparently, it's not particularly precise when aiming the proboscis into a flower. It is distributed in Nepal, northeastern India, southern China, and Thailand.

 

Callionima inuus last edited.jpg

Callionima inuus is certainly a very elegant hawkmoth thanks to the decorations on its forewings.

 

The scale pattern forms motifs which resembles a cover of cobwebs blended with small, dark and light brown wavy markings; there is also a patch of silver scales in the shape of a plump and twisted “Y”. The pattern is beautiful, but most of all indispensable, for perfectly disguising this moth in the environment where it lives. This species is well distributed in the entire Neotropical region, from Mexico to Argentina.

 

Phylloxiphia oberthueri last edited.jpg

Another master of disguise is Phylloxiphia oberthueri.

 

When in the resting position, hanging from a plant, this hawkmoth looks very convincingly like a bunch of dry leaves. This species is distributed through West Africa.

 

Hypaedalea insignis.jpg

Doesn’t Hypaedalea insignis look like the vehicle of a superhero character?

 

An innovative hawkmoth bat-car! But again, this pattern has not evolved to impress we humans; the amazing discontinuous and wavy lines and blotches, coloured with different tints of brown and grey, are all essential for making this hawkmoth hard to spot against the vegetation. This moth is distributed in West Africa.

 

And now, the history bit...

 

The Museum's collections are based on Sir Hans Sloane’s collection which was purchased by the British Museum in 1753. Amongst them were his entomological holdings, with around 5,500 specimens including Lepidoptera, and thus were the earliest Sphingidae housed in the Museum.

 

Sloane Coll. last edited.jpg

A drawer with specimens of Lepidoptera from the original collection of Sir Hans Sloane. The hawkmoths in this drawer (Smerinthus ocellata in the top left, Agrius convolvuli and Sphinx ligustri bottom left and right respectively) were collected more than 350 years ago and are amongst the oldest Lepidoptera specimens in our collections.

 

Afterwards, the earliest and most significant benefactors who presented Lepidoptera - and particularly Sphingidae - to the Museum were, Horsfield, the Honorable East India Company, and Museum appointees like Edward Doubleday.

 

Later 19th Century benefactors of major significance were Bates, Wallace, Stainton, Zeller, Bainbrigge-Fletcher, Hewitson, Leech and Godman and Salvin. And in the 20th Century the sphingids holdings of the Museum were to be enriched with the collections of Lord Walsingham, Swinhoe, Moore, Joicey, Levick, Lord Lionel Walter Rothschild, Cockayne and Kettlewell, Inoue and others.

 

List of donors.jpg

Some of the most significant donors of Lepidoptera (and particularly of Sphingidae) to the Museum.

 

The date of acquisition, the number of specimens and some of the history behind each of these valuable collections of moths and butterflies is often well documented, but it is much more difficult to know the exact number of specimens of any particular family that came with any of them. However, we know that the majority of the hawkmoths - around 45,000 specimens - came to the Museum in 1939 when Lord Rothschild bequested approximately 2.5 million specimens of Lepidoptera.

 

Rotschild Sphingidae Last edited.jpg

Lord Lionel Walter Rothschild was a keen naturalist who went on to amass one of the greatest collections of animals ever assembled by an individual. In 1939 around 2.5 million specimens of butterflies and moths from the Rothschild collection, were entrusted to the Museum in thousands of drawers. Two of these drawers, containing hawkmoths, are shown in the picture.

 

The Sphingidae collection, like the majority of the other Lepidoptera families, has since 1904 been housed in the Museum in 4 separated blocks:

 

Main Coll. Dr1.jpg

The Main Collection.

This is the reference collection and contains drawers with type specimens and representative series of any particular family, often of the oldest material. In the picture, one of the main collection drawers with the hawkmoth Callionima inuus.

 

Supplementary dr1.JPG

The Supplementary Collection.

 

It contains other specimens, belonging to any particular family, of identified material which arrived later and for which there was not space in the main collection. In the picture, one of the supplementary drawers with the hawkmoth Agrius convolvuli.

 

Accession Dr1.jpg

The Accession Collection.

 

It contains unsorted and often unidentified material which was later added to the family. In the picture, one of the accession drawers with different species of hawkmoths from the original Rothschild Collection.

 

British Coll. Dr1.jpg

The British & Irish Collection.

 

It contains specimens of the 20 species of Sphingidae occurring in the British Isles. In the picture, one of the British and Irish Collection drawers with the hawkmoth Daphnis nerii.

 

Only relatively recently we began to amalgamate all specimens from the main, supplementary and accession collections into one collection for each family. Each of the 5 curators in the Lepidoptera section is responsible, amongst other things, of the re-housing of one or more families of moths and butterflies.

 

With a collection of almost 9 million specimens and around 135 families of Lepidoptera to take into account the work to do can seem endless; it will certainly take a long time and a lot of effort before this is accomplished, but slowly and surely we are improving the care, storage and accessibility of our collections.

 

In August 2008, thanks to the generous sponsorship of the Rothschild family, the de Rothschild family, the John Spedan Lewis foundation, Ernest Kleinwort Charitable Trust and members of the public, the Museum was able to acquire one of the largest private collections of Sphingidae, the Jean-Marie Cadiou collection.

 

And it’s about this prodigious private Collection, containig a staggering total of around 230,000 specimens, the majority of which are sphingids, that I will be telling you in my next post. Make sure to come back then.


Thanks for reading.

Meet the hawkmoths

Posted by Alessandro Giusti Dec 17, 2013

In my last post I described one of my curatorial tasks here at the Museum: the re-housing of our extensive collections of hawkmoths, made up of around 289,000 specimens.

Untitled-1.jpg

The re-housing of the Museum’s extensive collection of hawkmoths will keep me busy for the next few months (did I hear someone say years?)

 

In this post I would like you to meet the actual stars of this project, the hawkmoths themselves. Hawkmoths belong to the Lepidoptera family called Sphingidae, a relatively small family if compared with other families in the order Lepidoptera; so far there are 208 genera and 1,492 species described. Untitled-2.jpgHawkmoths are insects belonging to the family Sphingidae in the order Lepidoptera. 208 genera and 1492 species of hawkmoths have been described so far. Top row (L-R): Deilephila elpenor (Elephant hawkmoth), Agrius convolvuli (Convolvulus hawkmoth), Elibia dolichus. Middle row (L-R): Cechenena sp., Hayesiana triopus, Agrius convolvuli (Convolvulus hawkmoth). Bottom row (L-R): Mimas tiliae (Lime hawkmoth), Hyles sp., Hyles lineata (Striped hawkmoth), Akbesia davidi.

 

Species belonging to this family usually have falcate (curved and hooked) wings and their body is characteristically streamlined. The majority of species have a very swift and agile flight, and hover rapidly in front of flowers feeding on nectar with their tongue, which is often very long.

 

Untitled-3.jpg

The long tongue of many species of hawkmoths is mainly used to feed on nectar from flowers or occasionally, as in the case of this Argentinean Xylophanes schreiteri, on sweet breakfast leftovers! This photo was kindly provided by Tony Pittaway. Check Tony’s interesting websites, Sphingidae of the Western Palaearctic and Sphingidae of the Eastern Palaearctic, for more information and pictures of hawkmoths.

 

Hawkmoths caterpillars are large and have a curved horn on the rear end. When disturbed, they usually rear up with their anterior segments arched, in a manner reminiscent of the Egyptian sphinx. These two larval features explain why these moths are also known with the common names of hornworms and sphinx-moths, while the common name hawkmoth refers to the rapid flight and falcate wing shape of the adult.

 

Untitled-4.jpg

Sphingid caterpillars have a horn of various shapes on the last abdominal segment. From top right clockwise: Cephonodes hylas, Dolbina inexacta, Eumorpha analis and Daphnis nerii (Oleander hawkmoth). All pictures by Tony Pittaway.

 

The beauty and elegance of hawkmoths have always been attractive to both scientists and the public; consequently these moths have become one of the most widely collected groups of insects.

The beauty and elegance of hawkmoths have always been attractive to both scientists and the public.

 

Hawkmoths are generally well represented in every insect collection, large or small, and they are frequently reared from caterpillars, which has helped in providing a great deal of information on their biology and life history. Most species are also readily attracted to artificial light sources and this helps in surveying them when conducting biodiversity inventories of an area, which in turn has provided us with considerable insights into their distributional patterns and ranges.

Untitled-6.jpg

Many species of hawkmoths are attracted to artificial light sources.

 

The following pictures, taken from specimens in the Museum collections, show the ample variation that exists in size, shape, features and wing patterns among the different species in this family of moths.

 

Untitled-7.jpg

The stunningly emerald green Euchloron maegera. This species is commonly distributed in all Sub-Saharan Africa.

 

Untitled-8.jpg

Oryba kadeni is another wonderfully green hawkmoth. It’s characterised by very large eyes and relatively short antennae. This species is found from Belize southward to Brazil.

 

Untitled-9.jpg

Some sphingids like dressing in pink, such as this lovely elephant hawkmoth (Deilephila elpenor). This species is relatively common and widely distributed. It occurs in all Europe (with the exception of northern Scandinavia, northern Scotland and parts of the Iberian Peninsula), eastward through temperate Russia to the Pacific coast, Korea & Japan. It is also found in China as far as the provinces of Sichuan and Guangdong. It is a common species in the UK.

 

Untitled-10.jpg

Leucophlebia lineata is another pretty hawkmoth sporting a series of pink, yellow and white stripes on the forewings. This species is found from Pakistan through India and Sri Lanka, to eastern and southern China, down to South East Asia.

 

Untitled-11.jpg

Neococytius cluentius is one of the largest hawkmoths with a wingspan that can reach 17cm, and a long tongue of up to 22cm. It occurs from Mexico to Argentina, and has also been recorded as a stray in north Illinois and south Michigan.

 

Untitled-12.jpg

The record for the longest tongue belongs to Xanthopan morganii subsp. praedicta, a relatively large hawkmoth found in Madagascar famous for its long proboscis used for probing on flowers to feed on nectar. Thanks to its long proboscis, which can reach 25cm, this moth is well adapted for feeding from the flowers of star orchids, in which the nectar is kept at the bottom of a very long spur. While doing so the hawkmoth secures the pollination of the orchid.

 

Untitled-13.jpg

On the other hand, the adult of the hawkmoths in the subfamily Smerinthini, such as this Laothoe populi (the poplar hawkmoth), have extremely reduced mouthparts and are unable to feed. This moth is well distributed across Europe, as far as southern Turkey and eastward through Russia, and as far east as Irkutsk. It’s probably the most common hawkmoth in the UK where the adults fly between May and July.

 

Untitled-14.jpg

Sphingonaepiopsis gorgoniades with its 2-3 cm wing span is the smallest hawkmoth. It occurs in some countries in South-East Europe, Turkey, Ukraine, Southern Russia, Kazakhstan, Kyrgyzstan and Afghanistan. It has also been recorded in parts of the Middle East.

 

Untitled-15.jpg

The hawkmoth Euryglottis aper reminds me a bit of one of those soft toy puppets. It is a very hairy species as it flies at elevation of up to 2800m in Venezuela, Colombia, Ecuador, Peru and Bolivia.

 

The Museum collection contains representive specimens of 207 genera and around 1,300 species of hawkmoths; a global coverage of 85%. Of the 289,000 specimens of Sphingidae held in the Museum collections, 113,000 are dry pinned and a further 176,000 are unset and still in their original envelopes. The  Museum's collection is certainly the largest and most complete collection of sphingid in the world.

 

In the next post I will be featuring more pictures and information on other species of hawkmoths and I will also give a little bit of history about the original hawkmoths collection of the Natural History Museum. I hope you'll be back then.

 

Thanks for reading and I take this opportunity to wish all the readers a Merry Christmas and a very Happy New Year.

I have always enjoyed taking part in Science Uncovered with its vibrant, interesting, exciting and revealing ambience.

 

As part of the European Researchers' Night, the Natural History Museum is one of the hundred institutions in 33 countries all over Europe to open its door for a night of discovery, learning and inspiration. The Museum's Science Uncovered for 2013 is here today, Friday the 27 September from 16.00 until Midnight, and it’s free!

 

Now, having said that, unfortunately I won’t take part in this year's event! I know this is very sad news for all my fans, or rather for all the fans of Lepidoptera, because they would have been the stars of the show, not me obviously!

 

Science-Uncovered-2-science-station-copyright-NHM.jpgThe Lepidoptera Station at last year's Science Uncovered.

 

But don’t despair! There will be lots of bugs on show, from large and shiny beetles to attractive and colourful butterflies and moths. Some of my entomology colleagues will be manning Science Stations so you can get up close to their favourite specimens and find out what they're working on.

 

Display_Drawers-png.jpgSome of the entomology display drawers you might be finding at this year's Science Uncovered.

 

One of the stations not to be missed is the iCollections projectdigitising the museum’s British and Irish Lepidoptera.

 

Let me tell you few things about this project and what you’ll find if you visit the station. The iCollections project is one of many digitisation activities currently undertaken by the Museum. The aim of the project is to make part of the vast entomology collections at our Museum more accessible to the public and to researchers.

 

POster Icollection.jpg

The iCollections project – digitising the museum’s British and Irish Lepidoptera.

 

Each specimen of British and Irish butterflies and moths from the Museum collections is currently being photographed, and the data on the label of each specimen is also photographed and transcribed. This is great news for curatorial and scientific purposes. In fact, once the specimens have been photographed they are re-housed into new drawers that will provide better conditions for many years to come.

 

The data from the specimens will also be extremely useful to examine the pattern of distribution of the species of British and Irish Lepidoptera, and how factors such as climate change and human impact through urbanization and intensive agriculture are affecting it. The data would also be valuable to assess the scale of the historical collections of the Museum.

 

Digitisers 1.jpg

Some of the digitisers at work.

 

Elisa.jpgOnce the specimens are digitised they are re-housed into new drawers.

 

The project started at the beginning of this year and so far the digitising team has managed to photograph more than 80,000 specimens and transcribe each of their labels.

Erebia drawer.jpgA drawer with specimens of Scotch Argus (Erebia aethiops), one of the 60 or so British species of butterflies currently being digitised.

 

Apparently it is a reliable and very productive team, digitising one specimen every 2.9 minutes!

 

So, tonight, at Science Uncovered, do pay the the iCollections project Station a visit. Meet Elisa, Gerardo, Jo, Lindsey and Sara, the digitisers. They’ll be happy to tell you more about this project, answer your questions, and since the process of capturing the data from the labels is rather interesting and complex, they will have some of these labels for visitors to have a go at transcribing and deciphering them! And there’ll be prizes to be won, if you are smart enough that is!

Team-jpeg.jpg

Meet the iCollections Project digitisers!

 

They will also have some drawers of their favourite species which have already been digitised. The digitising team will be located in the noisy Nature Games room (Marine Invertebrates Gallery), so listen out for our animal-themed buzzers!

 

Enjoy!

 

Science Uncovered takes place today, Friday 27 September at the Natural History Museum, London. Join us from 4pm to midnight.

In my last post, I described how and why I was in Borneo. Time now to feature some of the moths I collected...

 

First, let me illuminate you on light trapping as this is one of the most favoured ways of collecting moths, and indeed the method we have used to collect the majority of the ca. 2700 specimens of Lepidoptera we brought back from this trip. 

 

Moths seem to be more attracted by UV light than by normal tungsten bulbs and there are different devices used to lure them. A functional and unsophisticated device is a white sheet hanging on a vertical support with a UV light bulb suspended in front of it. One just stands next to it and enjoys the flying critters attracted by the light from the dark surroundings.

 

Pic 12.jpgOne of the 4 moth traps at the camp. We would spend hours every night, checking each of them in turn

 

A popular (and more expensive) method is to use designed light traps, such as the Robinson, Skinner and Heath traps. They still have UV bulbs but they are contained traps. There is a box under the light bulb where the moths fall after being attracted and confused by the light, egg cartons are placed inside the trap to create hiding places for the moths.

 

The advantage of using these types of light traps is that there is no need to stand around them because the moths that have fallen inside often remain in the trap, and are found the morning after, resting under the egg cartons.

The Robinson Moth Trap in the Wildlife Garden of the Museum. My colleague, curator Martin Honey, has been monitoring moths in the Garden since 1995 and so far 600 species have been recorded in this modest but vital green space in Central London

 

Designed light traps are generally used in temperate areas. On the other hand, in the tropics the white sheet is the favoured method because, in these regions, there are many more species of moths that are often more numerous and larger than the ones found in temperate localities. Therefore, it is much better to use a larger surface to collect them.

 

Collecting Moths in Borneo.jpg

It is still uncertain why many species of moths - and indeed the majority of species of insects - are attracted to artificial light sources, but I won’t delve in conjecturing here as a simple search in the web will give you plenty of hypotheses, none of which has been so far validated. However, below is a series of photos of some of the moths that were visiting our moth traps… absolutely gorgeous stuff (for me at least!)

 

Hypeninae1.jpg

Marapana flavicosta a moth of the Erebidae family with very long labial palps. This moth has been recorded only in Borneo in montane forests between 1200 and 1900 m. We have the type* of this species here in our Museum! 
* When a new organism is described and named, the specimen (or specimens) on which the author based the description becomes the 'type' (or types) for the species. Our beetler Beulah has a fun post about this here

 

Cyana.JPG

This pretty little moth that reminds me of a clown is very likely Cyana costifimbria, or a species very close to it. It also belongs to the Erebidae.

 

Acherontia lachesis.JPG

Acherontia lachesis, the oriental death's-head hawkmoth. An awe-inspiring moth and a skilled honey stealer! The adults (and even the pupae!) of the three known species of hawkmoths squeak when disturbed. Hear one here.

 

Barsine roseororatus.JPG

Barsine roseororatus - another erebid moth - frequently found in the forested and disturbed habitat of Borneo and Peninsular Malaysia. The type of this species is also here in the Museum!

 

Callidrepana argenteola.JPG

Callidrepana argenteola, a moth in the Family Drepanidae (the hook-tip moths). The caterpillar of this species resembles a bird dropping but unfortunately I could not find one to photograph. Again, we have the type specimen of this species in our collections.

 

Kunugia basinigra.JPG

Kunugia basinigra belongs to the family Lasiocampidae, commonly known as eggars, snout or lappet moths and this little fellow has certainly a snout to be proud of.

 

Lyssa Zampa.JPG

The Tropica Swallow Tail moth (Lyssa zampa), an uraniid moth distributed from North East Himalaya to South China and Thailand, also Philippine, Sulawesi, Borneo and the Malayan Peninsula. This species is relatively common particularly in montane forest, where it’s been recorded as high as 2600m on Mount Kinabalu. The caterpillar of this species feeds on plants of the Genus Endospermum in the family Euphorbiaceae. The type specimen of this species was also deposited in our Museum.

Tarsolepis sommeri, a moth in the family Notodontidae (the prominents and kittens), is relatively well distributed in various lowland forest areas of the Oriental region. The moth looks rather prickly with those amazing tufts of reddish scales and spiky hairs at the base of the abdomen… I feel itchy just looking at them! In some species of the Notodontidae family the females are known to cover their batch of eggs with scales and hairs from the abdominal tuft, to give them protection. This moth has been observed feeding from mammalian lachrymal secretion in Peninsular Malaysia.

 

I’m going to leave you with a collage I created with some drawings (not mine) of moths and an outstanding palindrome (a phrase that reads the same way in both directions) I found on the web. The palindrome is in Latin and translates: “We wander in the night, and are consumed by fire”, which I thought fitted particularly well with the subject of this post.

I hope you have enjoyed reading, and marvelled (as we did!) at the various amazing moths we encountered in Borneo.

 

I shall feature some more photos of nice invertebrates in my next post. 

Thanks for reading and see you then.

Hello, I am Alessandro Giusti, one the curators in the Life Sciences department of the Museum where I work alongside 4 other curators in the Lepidoptera section, which includes moths and butterflies.

The Lepidoptera section comprises around 9 million specimens housed in about 80 thousand wooden drawers. As a curator I look after part of this large and comprehensive collection. The groups of moths I’m responsible for include the hawk-moths (Family Sphingidae) and the slug moths (Family Limacodidae). Curators are the guardians of the collections and some of my main tasks include re-housing and labelling specimens, recording them into databases and answering enquiries made to our section about particular species of moths.

Rothschild type drawers like the one in the picture are used for housing the hawk-moth (Sphingidae) collection in the Museum. The species in this drawer is a Neotropical eyed hawk-moth called Smerinthus jamaicensis.

Curators also look after visitors who come to our Museum from other institutions to study certain groups of organism. Sometimes we supervise students who are here on work experience and volunteers who offer invaluable help. We often contribute to educational activities involving public and schools; occasionally we go out on fieldwork to collect new material, and to conferences where we can learn new skills and share our knowledge and work procedures.

So, I thought it was about time that the Lepidoptera section set forth into the informal world of blogging, and here it is my first post. I know you’ve been waiting for it eagerly...haven’t you? After all, ours is one of the largest sections in the Terrestrial Invertebrate Division of the Life Sciences Department in the Museum, occupying 4 of the 7 floors of the cocoon which houses the entomology and botany collections in the new Darwin Centre building.

 

"Only because many Lepidoptera specimens are rather large!", I hear some of my non-lepidoptera colleague entomologists murmur. Well that may be true, but with around 9 million specimens the lepidoptera collection is nevertheless one of the largest of the Museum’s invertebrate collections, which hold approximately 28 million specimens altogether.

The collection areas at the centre of the Cocoon accommodate more than 5 thousands metal cabinets. These cabinets, which have tight closing doors, contain thousands of drawers with our specimens and help us preserve our important collections for posterity.

 

In my next few posts I will talk about my last field work experience, which was in Borneo, so I hope you enjoyed this brief introduction and that you'll join me for the next post. See you soon and thanks for reading!
