Jurinia notata, Bigot (Bolivia)

Aug

2011

In this post I showed a Jurinia sp. from Bolivia, determined by Monty Wood. During a visit to the BMNH I discovered a species called Jurinia notata, Bigot (holotype in the collection). Here are some photos of the BMNH material, including the holotype (sadly not in good condition) and an additional specimen. * specimen photos ...

Archytas aurifrons, Townsend

Aug

2011

Last week I spent a happy afternoon at the BMNH, courtesy of Erica & Nigel in the Diptera department. I decided to concentrate on a few genera and try to identify a few neotropical specimens. My first was Archytas, a large genus with many very similar species, because I have a few quite atypical taxa ...

How to identify greenbottles in photos September 15, 2019
There are a few greenbottle tachinids and one of them (Chrysosomopsis aurata) is incredibly rare so I thought it might be worth showing how to identify it from the others. It is on the wing in late summer so could be easy to confuse for commoner species: Hairy eyes and strong erect bristles on […]
Tachinids that look like Eriothrix rufomaculata August 18, 2019
Eriothrix rufomaculata is an incredibly common fly in mid-summer, especially on any flowery meadows. The species is very easy to identify from the red abdominal side-patches, silvery face with projecting mouth edge, long costal spine, slightly shaded wings with a small petiole on the median vein. The only problem is that several other, rarer, […]
A quick guide to the new UK phasiines August 17, 2019
This year we have been lucky enough to receive records for 2 new species to the UK – Ectophasia crassipennis & Phasia aurigera. These both bear a resemblance to Phasia hemiptera and have been confused with them in the past so I thought I’d put together a few pointers on how to spot them. […]
How to split Tachina fera type tachinids in photos August 17, 2019
One of the most difficult problems is how to confirm/verify the identification of photos of flies that look quite like Tachina fera. I’d include in that group any of the following species: Tachina fera, Tachina magnicornis, Nowickia ferox, Linnaemya vulpina, Peleteria rubescens, Peleteria iavana & male Nemoraea pellucida. They’re all fairly large, bristly flies […]
Dexiosoma caninum vs Dexia vacua August 6, 2019
I always find that one of the hardest identifications to make from photos is the split between Dexiosoma caninum and the much rarer Dexia vacua. Dexia vacua is so rare that many experts thought that it was extinct in Western Europe so getting good, reliable records from photos is very important because it seems […]
