This is another large-bodied black species from the same coastal sandy environment by a small 'lake' (swamp) surrounded by pine trees referred to as 'Reserve naturelle de l'Etang Cosseau, Aquitaine, France,' taken yesterday, 14 September '14. It appears to be eating another asilid. This would be the 4th species from this region now, with neither sight nor sound of the previous three species yesterday (unless the meal is one of them).

Again, any assistance with an identification would be appreciated. Thanks in anticipation.

It has to be Andrenosoma atra, but we should see wings better. Prey is very probably Tolmerus cf pyragra.

Thanks for yet another quick ID. The best image I can provide of the wing, which isn't very good (seriously cropped; the fly was rather aloof), is attached. I am pulling what hair I have left out trying to attach a larger image ... but attachments and their size are challenging me of late and this attached image is probably no better than the composite I attached earlier (in terms of size and resolution). Thanks in anticipation.

It is almost enough : ) http://www.geller-grimm.de/andrenoe.htm#abb2 That is what i am looking for, first posterior cell closed and stalked. It seems to be closed but is it stalked?

My word. That's a handy illustration. Reinoud, the best I can manage is the attached (enhanced, seriously cropped). None of my images was particularly good for this species; I ran off a few from a distance using whatever settings the camera was at for whatever hapless beast I'd snapped earlier, but as I drew close and started to fumble with the camera to increase lighting and aperture it took off, so all I have are poor. Thank you again.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
