Curator of Lepidoptera

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.

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.

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

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.

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.

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.

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.

Re-housing hawkmoths

Posted by Alessandro Giusti Nov 5, 2013

Hello again!

 

Some of the enquirers during the recent #askacurator day event on Twitter were curious to know what curators do every day in their work. Well, I suppose it really depends on the type of collections in their care, and curators in a natural history museum might deal with different tasks compared to curators in an art collection for example.

 

Around 35% of mine and of my colleagues’ working time is dedicated to re-housing specimens, which is the transferring of pinned specimens from outdated or transitory drawers into new, more permanent drawers.

Many of the original drawers in our collections are not up to scratch with respect to the most recent guidelines of conservation and collections policy, therefore we are actively replacing them with refurbished or brand new drawers.

 

oct13.jpgTwo old types of drawers in our collection. We have already emptied & refurbished thousands of them, but there are still quite a few left to clear.

 

Once emptied, the majority of the old drawers are sent for refurbishment and then re-use in the collection; other old drawers, as well as many boxes that come in with acquisitioned material, are sold and the proceeds used to buy new drawers or furniture for the collection.

 

Many drawers in our collections still contain unsorted and often unidentified material; this is because new material has been regularly added to the Museum through fieldwork, donations and purchases since the very early days.

Specimens are also often donated to our Museum and others are purchased.

 

We always identify specimens before transferring them into new drawers along with the identified material already in the main collection. Eventually, when newly re-housed drawers are created, they need new labels, and their location, with other important details, are recorded in our electronic database.

 

These are all necessary steps if we want to make sure our collections are useful and easily accessible. If you consider that our section is made up of more than 80,000 drawers, it is crucial for us and for our visitors to know precisely where a particular drawer is located.

It also has a unique number; these details are all recorded in our electronic database so that specimens can be easily found in our extensive collection.

 

One of my current tasks is the re-housing of the entire Museum collection of hawkmoths (Sphingidae), which contains “only” around 114,000 specimens housed in about 2,130 drawers, and an extra 176,000 papered specimens, still in their original envelopes, waiting to be mounted.

 

Before August 2008 the Museum’s collection of Sphingidae contained ca. 60,000 pinned specimens, the vast majority of which were from the Rothschild Collection, dated pre-1930.

Then, 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 our public, the Museum was able to acquire one of the largest private collections of Sphingidae, the Jean-Marie Cadiou collection.

 

The Cadiou collection, which contained 53,000 pinned specimens and 176,000 unset and still in the original envelopes, doubled the size of the Museum's original holdings and has provided modern material that was lacking in our collection.

The Museum’s hawkmoth collection has been transformed by the arrival of the Jean-Marie Cadiou collection.

 

Follow me in the next few posts, where I will talk about both the original Museum and the recently purchased Cadiou sphingid collections. I will explain how the current curation of the important and comprehensive Museum’s collection of sphingid into modern unit trays and refurbished Rothschild drawers is taking place.

 

Thanks for reading.
