Thread subject: :: Asilidae (southwestern France) identified (Choerades & Asilus) (thread 1 of 2)

Posted by Steve O on 28-08-2014 10:17

This 'very large' (for me) species, ~25mm TL, was snapped in a coastal sandy environment by a small 'lake' (more swamp like) surrounded by a pine plantation; the precise locals being 'Reserve naturelle de l'Etang Cosseau, Aquitaine, France' on 18 (male) and 24 (female) August '14. I would have thought it relatively easy to identify, given its size, but I have since learned that there is no such thing as an easily identified asilid.

I assume all three are conspecific (male and female), but if not then they are certainly broadly sympatric.

Any assistance with an identification would be appreciated (thread '2 of 2' presents a second species).

(Ed. I have since learned all three are male, and that two species are involved, in separate subfamilies)

The Lower two belong to e subfamily Asilinae and both are males. Asilus crabroniformis. The one above belongs to the Lahpriinae and is also a male. It puzzles me a bit

My word, thank you so much for your prompt and authoritative reply. Obviously I need to take a course in 'insect 101' as I managed to confuse both sexes and species. I did manage several other pics of the upper individual - I'll attach those separately, in addition to the second of the two threads.

Here are two additional slightly different perspective variants of the upper of the three earlier specimens, should they be of any help in pinning the identity of the species down. I am afraid that I have a dozen lateral shots, but none from any other angle (the fly took off as I was already 'rather close' to it). Sorry about the resolution - the 200kb file-size limitation precludes me posting anything larger. Thanks.

Choerades ignea, male.

It has to be or closely related to it.
