Hello!
Who can help to identify this Bombyliidae? Found today near Frankfurt/Main Airport (Germany), heathland with large open sand areas. Size 12mm.
Is it Villa hottentotta or Villa spec....
Regards
Andreas

The males of Villa hottentotta have a dark back (see http://fauneflore...villa2.jpg), so I suppose the species is correct.

I'm not an expert, but it doesn't look like hottentota to me. The yellow abdominal bands seem too narrow.

Well, you can google several reliable pictures of males that have no yellow bands at all :). Therefore I am fully convinced that I photographed a Villa hottentotta male sitting before our house entrance in Berlin on 16 September (see below). Abdominal bands are hardly recognizable...

Villa is a very difficult genus. Misidentifications are easy to find.
I'm afraid there is no such thing as a reliable googled hottontota.
I'm saying, be cautious in this case

Dear Theo, of course you are absolutely right that misidentifications of photographed animals cannot be ruled out. I also admit that I am very cautious as to googled information. On the other hand, of the six species of Villa known in Berlin and Brandenburg, only V. hottentotta has been found since 1950. So the probability that my photo shows this species is rather high, and there is congruence with other sources that indicate only hardly recognizable abdominal bands in V. hottentotta males. Therefore Andreas' photo could show a V. hottentotta as well with rather high probability - it is a matter of statistics rather than determination, of course. I do not know the looks of the males of the rarer species and willingly accept correction by a specialist, if he/she is able to see more in the photo. So let's say "Villa cf. hottentotta";)!

Villa genus is not easy inside the Bombyliidae, but Usia spp. and Lomatia spp. seems to be more harder. ;)

Thank you all! Villa is realy a difficult thing. So, I will say Villa cf. hottentotta.
Thank you very much!
Sorry, I speak english not very well...:(

after carefully comparing your photos with my specimens i conclude that they cannot be identified. the only thing i can say is that they appear to be closer to my continental specimens of modesta than to hottentotta. Unfortunately i have no specimens of paniscus which, if truly a separate species, is very similar to both modesta and hottentotta.

one thing i can say for certain, any photo of this group of Villa which has not been collected, and in the case of males dissected, is very unlikely to be reliably named. even specimens are very difficult to name and this will remain the case untill the whole genus is revised.
