It not seems a conopidae fly but perhaps Culicidae family??

Taken today - 19th July 2006 in Silgueiros - VISEU. near window...

Title changed from "Very strange fly.... Conopidae family?" to "Very strange fly.... Vermileonidae - Vermileo cf. nigriventris", then to "Very strange fly.... Vermileonidae - Vermileo cf. nigriventris and Vermileo cf. vermileo"

Not Conopidae I think - possibly Asilidae?

Asilidae is very improbable... Asilidae doesn?t have a so recurved abdomen, they are much greater. They have legs much hairy. And the fly is much different than Asilidae flies.

I am that it somwhat resembles thinking Trichopeza longicornis of the Empididae, but several things are 'off'. Did you collect it? If so, a view of the full wing please. Can you also tell something about habitat, size, etc.?

Still, Jorge, this is an Asilidae flie... probably of the genus Dioctria.
Flies in this genus can be very small, slender and almost bare!
So be aware....

I thought that Asilidae cannot be so much bare like this one!My mistake. Raper was rigth.

(I thougth so, but we were all wrong

And so small like this one. The fly seemed like a mosquito!
Ok.

Size - about 6 mm.

Habitat - i found this one inside home... constantly fly against window like mosquitos...

If I could get images of wing venation for probable genus I could try to see what can it be. I have the specimen in ethanol 70%...

Not very good photo, but I hope it can be useful.

This is an unusual fly - genus Vermileo (Family Vermileonidae). The larvae of these flies make pits in protected, sandy areas to capture insects (like ant lions). (ID by Shaun Winterton, CDFA.)

If this confirms... diptera gallery will grow.

I thought in this fly unusual. The fly, as I say before, is very similar to a mosquito. (not to an asilidae fly). This fly enables for me to learn that there are, however, asilidae with not such hairy in legs. The other suggestion by Paul Beuk was a good one but I saw the photos of Empididae flies, and this fly haven?t a character that is very conspicuous in all Empididae. There is no an extension that begins in mouth (I don't know how it calls that structure.) like a proboscis... In true, I was not totally convinced, but now it seems more strong and consistent with this possible ID - Vermileo sp.

I saw some photos of Vermileo, and this one is very similar (with just a little difference, but essential the same): http://www.vialattea.net/spaw/Image/biologia/May2005/vermileo_vermileo.JPG

Now, I feel we are in the right way... but I want to hear more opinions!

Thanks to all!!

Two species in this genus are likely to occur in Portugal - V.nigriventris and V.vermileo. See http://perso.oran...vermi2.htm for pictures of V.vermileo. I suspect that your specimen is V.nigriventris, but only by elimination - I haven't seen a description!

Latin Nigriventris... (if i?m not wrong) means black womb. This fly is very dark indeed. More later, I will take more photos to get more crisp images and put them on gallery.

Anyone saw this fly? Is it, indeed, a rare sight?

i think the fly I spotted is really Vermileo vermileo. I'm waiting for confirmation.

Thanks!

I used this ancient thread so you could compare with the other Vermileo. See specially the abdomen. It is rather different.
