My first stacks 7

Apr

2011

Yesterday Malcolm Storey (bioimages.org.uk) brought over some new equipment he had just bought for photo-stacking, along with a ‘kit’ including a spare dSLR (3MP Nikon D100) and macro lenses. The real star of the equipment is Malcolm’s new StackShot – an automated system for racking a camera through pre-defined focus points and taking the photos ...

Back to the NHM again …

Jan

2010

Recently I had a few chances to go back to the NHM in London and work with the world Diptera collections – it was marvellous! I took along some of my larger & more spectacular specimens from North & South America and tried to identify them (with varying levels of success!). I also took lots of ...

Some Argentinian, Bolivian & Costa Rican tachinids 1

Dec

2009

A few of the more dramatic specimens from the neotropics a sample kindly donated by Martin Hauser 🙂 Identifications were derrived by comparing ot material in the NHM collections, London. EDIT (6/8/2011): I have just spotted that Monty Wood has demoted Trichosaundersia Townsend to a synonym of Epalpus – so have amended this article accordingly.

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 […]
Thelyconychia solivaga January 23, 2015
Recently I have been working on adding a new species to the British list to our key. Thelyconychia solivaga is a small tachinid that seems to live on fairly stony/rocky coastal sites and is very rare in the UK – in fact only 3 specimens have been found so far (by Laurence Clemons in Kent […]
