This fly was very common in early spring. The fly was very small, showed preference for Liguliflorae flowers. As far as I remember, similar flies are quite common in Europe.

I saw this fly only once. Is it Calliphoridae? Any suggestion for genus, this does not look sturcturally similar to Lucilia sp.

I apologize for the poor image quality. Is it Tephritidae or Pyrgotidae? How can I tell apart the two families?

1. Family Scatopsidae (they are midges, by the way). Not possible to say what species, or even genus, from this picture.
2. I am sure it is Calliphoridae. But if it is not Lucillia, then maybe [/i]Bellardia[/i]. There must be several others that are greenish, maybe even more in the East Palaearctic than in the West. ;)
3. This must be Tephritidae. In virtually all 'northern' Pyrgotidae the ocelli are absent and you can see ocelli shining in this picture. Otherwise, wing venation is almost always good to identify Tephritidae, with the subcosta clearly bent towards the costa (often at a [almost] straight angle) and clearly weakened after the bend.

Thanks Paul for your response.

As for Scatopsidae I think one has to be really a masochistic type to chose this family to study. Most members of this family are supposed to look quite similar to the image attached.

It would be very nice to include a Diptera anatomy page on this site. This also could include the wing vein pattens of many selected families.

It is on my list... if I ever get time to do it. ;)
