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my colleagues’ working time is dedicated to re-housing specimens, which is the transferring of pinned specimens from outdated or transitory drawers into new, more permanent drawers.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

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.

Not only Leps!

In previous posts I described how I have been lucky enough to travel to Borneo on fieldwork for the Museum. I explained how moths are collected using light traps, and we also got to meet some of the moths I found during this trip.

 

The four light traps at our camp were obviously very popular with many different species of moths, but when you put up a light trap in areas which are biologically rich - and this is particularly true in tropical regions - a whole range of other insects show up too.

Many species of beetles, attracted by the bright ultraviolet light of our traps, kept the coleopterists on the trip, Beulah, Max and Howard, busy collecting their favourite invertebrates.

Some interesting and rare species were sampled in this way, including the magnificent Chalcosoma, a dynastine beetle.

The striking dynastine beetle Chalcosoma moellenkampi (female on the left and male on the right) was one of the many interesting and rare insects visiting the light trap.

 

Other frequent visitors to the light traps were mantises and crickets which, true to their predatory habit, invariably found a tasty prey to feed upon. Hefty cicadas and large bees and wasps were also numerous; their blatant cries and unpredictable flight paths were a source of constant distraction for us, as we tried to concentrate on less vociferous and placid species. Many flies, stink-bugs, frog- and leaf-hoppers, parasitic wasps and flying ants and termites were also regular visitors at our light traps.

A great variety of other species of insects are commonly attracted by light traps.

…and even a terrestrial crab!

 

At times, it seemed that the arthropod fauna of the entire neighbourhood was paying a visit to our light traps and every night we were pleasantly surprised to find a new species of moth or beetle appearing at the trap for the first time. The number of insects visiting the traps only decreased during a few nights at the end of the trip; this is because the moon was full and clearly visible from early evening to late night. However we were still up late, trying to collect the few interesting species which, untouched by the resplendent show in the sky, were still paying a visit to our comparatively dingy traps.

There is no way a light trap can compete with such a large and incredibly luminous celestial body!

 

During the mornings, while my colleagues were checking the Flight Interception and Malaise traps we put up in the forest, or collecting beetles using other methods, I was busy pinning the moths collected the night before.

This has definitely been an amazing field working experience and judging by the number of specimens we have brought back a very successful one too. We’ve collected in the region of 13,000 specimens, which, after having gone through the freezing process, will soon be ready to be sorted and identified, mounted and labelled, electronically recorded and finally incorporated in our ever growing collections.
