Staph we did this summer

Posted by Blaps Nov 30, 2014

Emeline Favreau, our long-standing volunteer and recently graduated MRes in Biosystematics from Imperial College, London, and Josh Jenkins Shaw, also a long-standing volunteer and MSc Entomology student at Harper Adams share a little of what they did at the Museum this summer.

 

We have been quite busy this summer investigating the diversity of beetle infra-order Staphyliniformia. This is the group of Coleoptera whose popular members have short elytra (Staphylinidae), like the devil's coach horse. Using the same method as in the Biodiversity Initiative, we have used their DNA to unveil the evolutionary relationships between species.

The idea was to understand the evolution of this group, as scientists have yet to pin point the exact placement of some families in the tree of life, like Pselaphidae for example. If we identify the close relatives to the Pselaphinae, we would be able to understand how this family evolved from a common ancestor. How would this common ancestor look like? What would have been its preferred habitat? What would it have been eating? These are the questions we want to answer.

 

In the laboratory, we first get the DNA from Staphyliniformia specimens and we spend (quite a lot of) time on a computer to figure out their evolution from molecular data. We use algorithms that convert the DNA into meaningful data, which in turn is used to create the tree of life (see the recent research on all insects). And this is when Josh comes in, as a fantastic volunteer in the molecular lab and here at Origins:

 

“I'm Josh, a volunteer in the molecular systematics lab at the NHM but I have previously volunteered in the beetle collection during the summer of 2011. Now I'm bringing the two areas together to complement each other.

Josh might be a little confused; this looks like the ladybird section; or is he just looking for out-groups?

 

This summer I've been working with MRes student Emeline Favreau trying to understand the phylogenetic and evolutionary relationships of the infra-order Staphyliniformia (that is the series that contains the Histeroids, Hydrophiloids and Staphylinoids - basically a lot of beetles - more than 74,000 described species!!)

 

Other than looking at DNA sequences on a computer and scratching my head a lot when faced with using odd computer programmes, I have been trying to identify specimens which have had their DNA sequenced already. Building phylogenetic trees is brilliant, but they only really make sense when the end points (nodes) have a name at the end! Identifying beetle specimens is often made much easier when you have a reference collection to hand, so it's rather fortuitous that the Coleoptera collection is two minutes' walk from where I've been based!

 

I also assisted Beulah with putting together a Staphylinid loan which mostly consisted of specimens belonging to the genus Bolitogyrus - a geographically interesting lineage, but they are also extremely cool looking!

I recommend having a read/look at the photos in a recent taxonomic revision by Brunke & Solodovnikov:

 

A revision of the Neotropical species of Bolitogyrus Chevrolat, a geographically disjunct lineage of Staphylinini (Coleoptera, Staphylinidae)

 

This revision uses NHM specimens and also describes many new species. Some of the NHM specimens were collected over 100 years ago and form part of the BCA collection.

As the countdown to Science Uncovered 2014 begins, we have been busy behind the scenes thinking about how we talk about our science. How we make it interesting to YOU and how we can get YOU involved.

 

Making science accessible to all is one of our big challenges as a leading natural sciences organisation. With upwards of 80 million specimens (10 million of those are beetles!) we have a wealth of data that if only it were publicly mobilised would be even more relevant to the world at large, not just researchers in the natural sciences. Essentially we want to share our data; but, if I told you for our 10 million beetles we have just six curators, how is it even conceivable for us to make that data accessible?!

 

It took the creative mind of Ivvet Modinou the Museum's science communication manager and one of the leading people behind the Museum's participation in the EU's Researchers night to come up with a grand plan that would unite scientists and our visitors (YOU!) in making our data ever more accessible to the world at large. A few meetings later with Max Barclay (Coleoptera collections manager), Ben Scott (Data Portal Lead Architect) and Laurence Livermoore (digital analyst) the fledgling idea became reality.

Taking our Beetles and Bugs Flickr pages as a model the idea developed into something much more ambitious, and we want YOU to help us achieve this on the night! All you need is to turn up, be able to read and possess a smartphone or tablet – easy! Are you ready?

 

Ben explains, 'Live on the night we'll be showing the entire process of digitising specimens; from transcribing a label & crowd sourcing to data outputs via the Data Portal and visualisations.'

 

So how are we going to do this?


First we take a photo of the specimen which we upload to our Flickr site. After this a transcription app pulls the image from Flickr, and we ask any willing member of the public to transcribe the image. Once transcribed these data are added to our "Science Uncovered Transcriptions" data set. Then it's up to you to tweet about your good work!

 

You can even do it whilst having a beer! Don't worry if you're concerned about data accuracy, we've thought about that too.  Every specimen label will be transcribed multiple times, building up the level of accuracy and we will have our experienced team of digitisers and geo-referencers on hand to answer questions. After the event the dataset will be cleaned up by Ben, and then Max and Ben will work with the data to prepare it for entry in to our Museum database (imagine a database that has to cope with 80 million records!).

 

So this is very exciting and a new way of looking at and accessing our collection. The Coleoptera team have already come a long way with digitisation of specimens. Our beetles and bugs Flickr page has been online since 2012, has had well over a million visits, and has led to an unprecedented rise in interest in our collections as a result. Not only do we use it to highlight specimens of special note, like this one collected by Alfred Russel Wallace,

Species was named after the collector, a Mr. Lamb, but Wallace translated his name into Latin.

 

but also to get specimens identified. Each year we receive upwards of 50,000 specimens into the collection from recent collecting trips such as this beetle collected by me and Max in Borneo in 2013.

Identifying these beetles can be a lengthy process so putting them up online allows a first look for researchers and taxonomists all over the world. If they see something they think is interesting we can then send those specimens out on loan; eventually they will be returned identified and quite often there will be a few new species too!

Hillery Warner (beetler and top specimen mounter) was one of the pioneers of our Flickr site, and here she explains why we began this most ground-breaking of projects.

 

hillery bugs.jpg

Sometimes, beetles just aren't enough to keep Hillery busy; she has to dabble in the dark arts of Mantodea too...

 

"The Flickr project started off as a way to see if our unidentified material might be voluntarily identified by specialists around the world if we provided it online.  While we did have some success with this, the project quickly evolved into not only a fantastic public outreach outlet, but also a way of maximising the usefulness of our digital loans.

 

Scientists scattered across the globe need to see specimens in our collection in order to do their work- identifying, describing, and revising life on earth.  Sometimes they need to take a really close look at every detail of a specimen, which means they have to fly over to London, (which is expensive), or we need to actually put the insects in a box and post them out on loan.  But sometimes they just need "to see it".  This is when the very best option is to take a picture and send it.  Job done.  We call that a "digital loan". Before the Flickr site, we would email the attachment to the scientist who asked for it, and we were the only people to ever see it.  What a waste!  These people are working on cool stuff.  And you should get to see it, too.  So now, we put it out onto Flickr for you too!"

 

Since the inception of our Flickr site the Museum has began digitising collections on an even larger scale and now employs a team of people to image and transcribe. They work on dedicated projects; the most recent one for Coleoptera being the digitisation of 9000 specimens of beetles belonging to the family Chrysomelidae (the leaf beetles), of which many species are known to be economically important crop pests, as part of the Crop and Pest Wild Relatives Initiative.

 

Here's some of the digitisation team you will meet on the night,

So, we look forward to working with you on the night! Let's see how many specimens we can transcribe… and remember, we need you to help make this a success!

This is the first in a series of blogs about the Museum’s Biodiversity Initiative and its ambitious endeavour to research novel ways of describing insect species (though naturally our priority is beetles!) in tropical forests around the world. We endeavour to bring together DNA methods and traditional morphological taxonomy to help us make statements and answer questions on species richness and turnover, diversity and distribution as well as simply increasing our knowledge of the incredible (and seemingly infinite) diversity of species in the world’s most threatened of habitats, primary tropical forest.

As fieldwork and collections co-ordinator for the Panama project I had to make sure that any fieldwork we undertook was approved and regulated by the relevant authorities. As one of the world’s foremost institutions in natural history, we are governed by a strict code of practice and adhere to international regulations on Access and Benefit Sharing and the Convention on Biodiversity.

 

In order to fulfil our obligations to the countries and institutions we collaborate with, a permit will be agreed upon setting out the conditions and commitments we must abide by in order to collect insect specimens for scientific research.

 

On our collecting trip to Panama in March and April 2014 we were fortunate to have the opportunity to collaborate with the University of Panama, and Panama Wildlife Conservation - without their assistance this project would not have been possible.

 

Fast-forward four months and today is an exciting day. Finally, after months of tense negotiations with international couriers, many phones calls, texts and emails flying between Panama and the UK, we are finally expecting a very large package of carefully preserved insects…Those long minutes spent on hold to our excellent couriers listening to 'Aint no river wide enough' - on a loop, paid off...

The very wide and deep river we crossed everyday to get to our field site. Foreground, Luis Ureña, one of the project leaders in Panama and background, Julien Haran, with hopefully dry underpants!

 

So, this is a backwards way of introducing a major project on beetle genetics and Natural History Museum collections development but most importantly a very big thank you to all the amazing people and organisations that helped us realise this project.

 

In particular we want to thank Vayron De Gracia & Bernardo Peña who we kind of left behind in the field in Santa Fe NP once our three weeks of collecting were over! As part of our commitment to collaboration with Panama, it was important to us to exchange expertise and knowledge; essentially capacity build. Our intention was to collect in the dry and rainy season which meant being in the field for at least 2 months (my tolerance for roughing it extends to three weeks maximum!) and also there is always a financial constriction on how much time we can spend in the field.

A somewhat nervous looking team we are about to leave behind to continue collecting. From left to right: Vayron Cheffin's Father, Bernardo, Julien, Cheffin, Senior Pastor; and most importantly, the faithful Rosinante!

 

It was an ideal situation to find two excellent, willing and able biology students from the University of Panama; eager to accompany us on this trip into the darkest interior of Santa Fe National Park to a locality previously never collected for insects before.

Vayron and Bernardo didn’t seem to mind living in a chicken pen and eating SPAM for weeks at a time (more on that in later instalments!) so they proved the ideal field companions! We trained them in biological recording techniques and beetle family identification which helped them to put the theory learned on their university course to practical use in the field. When we left (just on the edge of the dry season) Vyron and Bernardo stayed on for another five weeks to continue collecting using the methods they had learned from us.

And thank you Vayron and Bernardo; we can’t wait to start working on the specimens and finding out more about the beetle biodiversity of the beautiful country that is Panama!

 

Report on the training of Panamanian field assistants

By Vayron De Gracia & Bernardo Peña

 

The collecting of insects developed in the Santa Fe National Park, allowed us for the first time to learn about collecting methods and about the traps used to capture insects in tropical forests. This was the first time we worked with these type of traps, in understory (FIT and Malaise), upper canopy (SLAM), on the ground (Pitfall) and Winkler traps (leaf litter); and the Yellow pan traps at ground level to capture other orders of insects such as Hymenoptera.

 

As undergraduate biology students at the University in Panama, we have only been taught about trapping for aquatic insects. Another important aspect was the way the traps were deployed on a plot by plot grid system that can be used in any tropical forest anywhere in the world, not just Panama. We did not know about this methodology to capture insects, in summary this was all new knowledge for us.

This is the first Project of its kind in Santa Fe National Park (SFNP) and it has been an exciting experience to be part of it from the very beginning and to witness how traps need to be deployed -  the organization and methodology used in the field with experts from the Natural History Museum. Moreover, the data generated as a result of this study will be new for the SFNP and for Panama regarding the entomological fauna.

When Google maps go wrong - our plot design; co-ordinates for Santa Fe.

 

Now we have the capacity to transfer the information to other people on how to conduct insect collecting and to collaborate with other scientist in the future. It was also valuable to deal with the traps and collecting in the following months after the team from the Natural History Museum departed. For example, the harsh climatic conditions, some landslides near the path to the plots, and the damage to the SLAM traps.

 

On one day of normal field collection, we left the Isleta camp to empty our traps and we were astonished to find the SLAM traps of Plot 1 had some holes in the sheet, and the plastic pots were perforated (see pics). Our first guess was that the guilty guys were crickets and woodpeckers! We were really worried because we were alone in the field and had to solve the problem in situ, after all we were in charge of collecting in the field. Masking tape was the temporary solution to the damage of the traps and luckily it worked out until the end of the dry season sampling in Santa Fe.

Funny note:

Frequently communication was a barrier from the beginning since our level of English was really poor. However there were always funny moments and anecdotes. For example “Chefin” our field guide use to say “Hay cantidad” (There is a lot) of anything he thought could be important for us. At the end this phrase was learnt by Julien Haran who one day working toward the plot claimed: “Hay cantidad”, referring to many cockroaches wandering on the leaf litter…

It’s Science Uncovered time again beetlers! We can’t wait to show off our beetles to the thousands of you who will be visiting the Natural History Museum on the night. We'll be revealing specimens from our scientific collections hitherto never seen by the public before! Well, maybe on Monday at the TEDx event at the Royal Albert Hall we did reveal a few treasures, including specimens collected by Sir Joseph Banks and Charles Darwin, as seen below.

Last year we met with about 8,500 of YOU – so that’s 8,500 more people that now love beetles, right? So, as converts, you may be coming back to see and learn some more about this most speciose and diverse of organisms or you may be a Science Uncovered virgin and no doubt will be heading straight to the beetles (found in the DCII Cocoon Atrium at the Forests Station).


This year the Coleoptera team will be displaying a variety of specimens, from the weird and wonderful to the beetles we simply cannot live without! Here’s what the team will be up to...


Max Barclay, Collections Manager and TEDx speaker
For Science Uncovered I will be talking about the diversity of beetles in the tropical forests of the world. I have spent almost a year of my life in field camps in various countries and continents, and have generally come back with thousands of specimens, including new species, for the collections of the Natural History Museum. I will explain how we preserve and mount specimens, and how collections we make today differ from those made by previous generations.

The Museum encourages its staff to be respectful of and fully integrate with local cultures whilst on fieldwork. Here is Max demonstrating seemless cultural awareness by wearing a Llama print sweater in Peru.

 

I will also talk about the Cetoniine flower chafers collected and described by Alfred Russell Wallace in the Malay Archipelago, and how we recognise Wallace’s material from other contemporary specimens, as well as the similarities and differences between techniques used and the chafers collected in Borneo by Wallace in the 1860s, Bryant in the 1910s, and expeditions of ourselves and our colleagues in the 2000s.

 

Lydia Smith and Lucia Chmurova, Specimen Mounters and trainee acrobats
As part of the forest section at Science Uncovered this year we are going to have a table centred on the diversity of life that you may see and hear in tropical forests. Scientists at the Natural History Museum are regularly venturing out to remote locations around the world in search of new specimens for its ever expanding collection.

We will be displaying some of the traps used to catch insects (and most importantly beetles!) along with showing some specimens recently collected. We will also have a sound game where you can try your luck at guessing what noises go with what forest creatures. Good luck and we look forward to seeing you!

 

Hitoshi Takano, Scientific Associate and Museum Cricketer

Honey badgers, warthogs and Toto - yes, it can only be Africa! This year at Science Uncovered, I will be talking about the wondrous beetles of the African forests and showcasing some of the specimens collected on my recent fieldtrips as well as historic specimens collected on some of the greatest African expeditions led by explorers such as David Livingstone and Henry Morton Stanley.

Beulah Garner, Curator and part-time Anneka Rice body double

Not only do I curate adult beetles, I also look after the grubs! Yes, that's right, for the first time ever we will be revealing some of the secrets of the beetle larvae collection. I can't promise it will be pretty but it will be interesting! I'll be talkng about beetle life cycles and the importance of beetles in forest ecosystems. One of the reasons why beetles are amongst the most successful organisms on the planet is because of their ability to inhabit more than one habitat in the course of their life cycles.

On display will be some horrors of the collection and the opportunity to perhaps discuss and sample what it will be like to live in a future where beetle larvae have become a staple food source (or entomophagy if you want to be precise about it)...go on, I dare you!

 

Chris Lyal, Coleoptera Researcher specialising in Weevils (Curculionidae) and champion games master

With the world in the throes of a biodiversity crisis, and the sixth extinction going on, Nations have agreed a Strategic Plan for Biodiversity. The first target is to increase understanding of biodiversity and steps we can take to conserve it and use it sustainably. That puts the responsibility for increasing this understanding fairly and squarely on people like us. Now, some scientists give lectures, illustrated with complex and rigorously-constructed graphs and diagrams. Others set out physical evidence on tables, expounding with great authority on the details of the natural world. Us – we’re going to play games.

 

chrisgameweb.jpg

Ecosystem collapse! (partially collapsed).

 

Thrill to Ecosystem Collapse! and try to predict when the complex structure will fall apart as one after another species is consigned to oblivion. Guess why the brazil nut tree is dependent on the bucket orchid! Try your luck at the Survival? game and see if you make it to species survival or go extinct. Match the threatened species in Domino Effect! Snakes and ladders as you’ve not played it before! For the more intellectual, there’s a trophic level card game (assuming we can understand the rules in time). All of this coupled with the chance to discuss some of the major issues facing the natural world (and us humans) with Museum staff and each other.

'Why did the entomologists choose the rice weevil over the acorn weevil?'

One last thought, things can get a bit out of hand late at night in the Museum, it's not just the scientists that like to come out and play once a year, it's the dinosaurs too...

 

We look forward to meeting you all on the night!

Well 'tis the season - fieldwork season that is, and also the rainy season in Tanzania - which is NOT the season for fieldwork! But, if you are Hitoshi Takano, and determined to find that elusive species new to science, then needs must. This week, our fledgling entomologist has flown the NHM Coleoptera nest and managed (against the odds) to send us his 'notes from the field'. Here are the highs and lows thus far:

 

“For the rain it raineth every day”

 

It has been tough. It has seemed like everything has been against us – a long and drawn out April Fool’s joke that Feste in Twelfth Night would be proud of. The wet season in tropical Africa really is a most unforgiving place. Especially up in the mountains.

Our drive from Dar es Salaam to the village of Maskati in the Nguru Mountains should only take 7 hours or so in normal conditions; it took nearly 14 hours this time. The roads leading up to Maskati are winding and contain some pretty challenging uphill hairpins and turns with huge 100m drop offs. Dangerous enough in the dry season, let alone with the torrential rainfall. The deforestation on these slopes don’t help at all. The topsoil just erodes away and flows into the rivers; landslides are not uncommon in this region.

 

 

Half way up to Maskati the back wheel of our trusty vehicle slipped off a concrete bridge. The whole vehicle ground to a halt with its weight bearing down solely on the differential! It took us nearly 2 hours of lifting and pushing with the help of the locals to get the car out. We thought this was bad enough; 200m further up the road, up an especially tricky uphill turn, the vehicle nearly flipped onto its side; it slipped down hill and ended up with its front left tyre completely off the ground! There were many points along this road where we had to unload the kit from the vehicle, reload it only to get stuck 100m further down the road. There were times where we thought it would just be impossible to make it to the village due to the atrocious roads. But Maskati and the Ngurus are well worth the effort. With the sun setting behind the mountains, the village must be one of the most beautiful places in the world. I would guess this is the kind of place James Hilton imagined when he described Shangri-La in Lost Horizon. The air is cool and refreshing. Maskati has been known to the Europeans for over a century. The mission and the church in the village were built by the Germans in 1909 and are still the pride of the village.

 

The walk into the mountains is also very tough. Two serious up-hills interjected by fast rivers flowing over slippery granite. Having overcome this obstacle, one reaches an incredible ridge at about 2100m. Beyond this ridge is a 200m drop off into what feels like Jurassic Park; a prehistoric forest with wonderful streams and rivers which contain many endemic frogs and chameleons, tree ferns, mosses and lichens. Many of the neighbouring forests have been logged out but because it is so difficult to get here (and to get the timber out) this area has escaped the deforestation.

To rub salt into the wound, this long walk was undertaken during a torrential downpour! I made a massive hash of packing my kit and because none of my clothes were in dry bags, absolutely everything got wet! Thank goodness we had three hours sunlight on top of the ridge to dry my clothes. I was not very happy with my schoolboy error!

 

 

During my time in the Ngurus it really did rain a lot. If we had less than 10 hours rain in the day, we were lucky; on bad days, it rained for 12 hours and more. Cold and wet. Nothing dries - putting on wet clothes in the morning has got to be one of the more unpleasant experiences when in the field.

The wet season also means that two of my fears become a palpable reality. Firstly, lightning and thunder which in their own right are extraordinary spectacles, but camped perilously on an exposed ridge with quite a lot of metal from all our equipment is not in the least bit amusing! Secondly, slugs and snails – my inordinate fear. They are everywhere. On the forest floor, on my tent, even in my tent. When walking at night looking for insects, every leaf you look at and every log you turn over, there is always some filthy slimy creature waiting for me! Give me spiders and scorpions any day!

Having managed to get up to the mountains and to base camp in the forest, we found to our despair that the generator we bought with us did not survive the journey. Light trapping is such an important weapon in an entomologist’s armoury that without it, comprehensive collection becomes very difficult. We painstakingly had another generator sent up into the forest and although it seemed like it was working, this too failed to light our Mercury Vapour lamp! Unbelievable! Other things which decided to die at crucial points included our inverter/battery charger, the choke for one of the actinic tubes and a digital camera. At this point it seemed very clear that it was worth cutting our losses and returning to Dar es Salaam to sort out our electrical problems; we really need it working for the rest of the trip. It is a terrible shame but we will be returning to the mountains towards the end of the trip to light trap high in the cloud forest.

 

I will now be heading south to the Udzungwa Mountains where elephants and buffalos await – and no doubt, more rain!

Next time, we see some Tanzanian beetles encountered along the way...

Hello,

 

As I promised, we have over two hundred years of stories to share with you about beetles, collecting and general shenanigans here at the Natural History Museum. Here is one such tale:

 

In a news month that sees £53 million being paid for a Chinese vase found in a house clearance in Pinner, perhaps we have all looked a bit closer at what might be lurking at the bottom of a cupboard, in the attic or the cellar...

 

One such Coleopterist did just that, but perhaps was a little disappointed to find, not a priceless Ming vase, or a jewel to rival the Hope diamond, sadly no, rather a collection of beetles from an Imperial College 1960 expedition to Ghana!

 

This expedition in 1960 yielded a fantastic collection of beetles, which, donated by the coleopterist (who shall remain nameless)  was accessioned into the Museum's collection in 1967. 1967! Some years later, no doubt whilst searching for some suitable pieces to flog on Cash in the Attic, found some long forgotten collecting boxes under his bed...

 

This week the collection is reunited in its entirety and we are now in the process of very meticulously placing accession labels on each specimen from 1967!

 

Here's one of our excellent volunteers, Gabrielle, moving the beetles from their original collecting boxes to unit trays ready for incorporation into the main collection, and just one of the collecting boxes, in very good condition.

Welcome to the Beetle Blog!

Posted by Blaps Nov 17, 2010

Hello beetle lovers - and if you are not converted yet then hopefully, as you follow this Blog you will become as enchanted and fascinated as I and my good colleagues here in the Coleoptera & Hemiptera section of the Entomology department!

 

You may or may not know that 'Coleoptera' is the scientific name for the beetles. This comes from the Greek, meaning 'sheathed wing' quite literally koleos = sheath and pteron =wing. It is because of this morphology that the beetles are such a successful group. Not only do they have a pair of protective hardened wings (known as elytra) to protect the wings and body underneath, they also have a pair of flight wings which means they can disperse easily and flee from predators.

 

Not all the beetles are capable of flight and their wing cases may be fused together, this is true of many of the ground beetles (the Carabidae) which is the group or family that I work on here in the department. There are many families of beetles, at least well over a hundred, this figure changes over time with taxonomic revision (taxonomy = the classification of biological organisms).

 

There are six curators of beetles here in the section who all care for the 9,000,000 specimens we hold in our collection - yes, that's 9 Million specimens of beetles! As well as the curators we have researchers from the UK and all over the world who visit the collection as well as a merry band of volunteers and students. I'll be asking my colleagues to contribute to the Blog as there is no shortage of stories or interesting projects to be shared with you.

 

Currently I am working on the revision and recuration of a subfamily of the Scarab beetles, the Phanaeini. These beetles are one of the groups of dung beetles (we all love the dung beetles right?!), and for creatures that make a living out of exploiting that most abundant of natural resources - poo - they are really rather attractive!

These fantastic metallic green beetles Phanaeus (Notiophanaeus) achilles were curated by my ex colleagues CG & NDS, and are found in South America: Peru and Ecuador. They are interesting in that males and females work together in excavating a tunnel under the 'dung' taking some of the dung with them in order to lay eggs into. When the eggs hatch the larvae have a plentiful food resource. All dung beetles are important nutrient recyclers in the natural environment.

 

 

 

 

 

 

 

 

Also, this group gives us great examples of 'sexual dimorphism' (difference in form between males and females).  Below you can see the horned male on the left and the 'hornless' female on the right of the species Phanaeus (Notiophanaeus) achilles. This horn we would term as a sexual ornament, it may be used for attracting a female as well as fighting off competition from other males for the females' attentions!

If you are interested in beetles, one of the publications we used to recurate the group is this excellent text by Patrick Arnaud.
