Building a key to the British Alexeter | Identification Trainers for the Future

In the final post of our short series on the curation placements of our Identification Trainers for the Future, Chloe Rose gives us an insight into the work she has been doing in the Hymenoptera department. The Hymenoptera include all bees, ants and wasps, but Chloe has been focussing her work on the parasitic wasps, of which there are a surprising number in the UK.

I have been spending the last 2 months of my traineeship in the Hymenoptera department with Dr Gavin Broad (Senior Curator of Hymenoptera, specialist in Braconidae and Ichneumonidae). Here I have been working on a genus known as Alexeter, a group of wasps which parasitise sawflies.

These wasps fall into the Mesoleiini tribe which is part of a large subfamily known as Ctenopelmatinae. There are around 6,000 known species of parasitic wasps in the UK, a staggering number which is a huge portion of our insect diversity. However, little is known about many of these groups and few of these species have well illustrated identification keys available, making the area of study considerably less accessible. This is why I am helping Gavin to construct an easy-to-use identification guide for this poorly understood group of wasps.

Reaching the halfway point | Identification Trainers for the Future

Our initial cohort of ID Trainers for the Future are nearing the end of Phase 2 of their 12-month long traineeship – Chloe Rose provides an update on the work they’ve been doing so far:

Over the last six months you will have heard all about the vast array of workshops we’ve had delivered to us by the Museum’s experts, the beautiful parts of the country we’ve visited for field trips and the various different projects we’ve all been working on. It has been an action packed, whirlwind and we’ve all gained so much. But it’s now time to wrap things up as we head towards Phase 3 of the traineeship. This will mean the five of us going off on our separate ways for three months, to spend time with one of the Museum’s curation teams.

Here is where we will get the opportunity to refine our identification, fieldwork and curatorial skills to one particular species group. Between us we will be covering beetles, dragonflies, lichens and flowering plants. My project will involve working on the hymenoptera collections and looking at an understudied subfamily of parasitic wasps. I will be required to sort and describe the species and look to writing a comprehensive key for identification purposes. Watch this space for future updates on how our curation projects are going. For now, though, back to what we have been doing during August.
