Hello!

Is it possible to give an ID? At house wall, northwest Germany, length about 3 mm. Thanks in advance!

Hello!

I did not have much hope about the other Sphaerocerids,

but I thought that these dark veins were rather distinctive...

Hi Juergen - I'm not sure about the species, but the appearance of the wings suggests that this is a freshly emerged individual, and it is possible that the wings will change in colour as it matures. I would expect that the milky (pale grey) colour will disappear, and that the dark shading might spread so that most of the wing membrane is darkened.

I see many photo's of Sphaeroceridae on Diptera.info that are not identified.
What is important to take photo's of...legs or wings or something else, to get maybe an identification..of genus or species?
Or are they even whit good photo's difficult....

Hello, Tony and Joke!

Thanks for your comments. If it was a freshly emerged individual, then there were several of them at the wall. They looked rather similar as the frequent Lotophila atra, often found in the last weeks, but were smaller and had those distinctive wings. Therefore I thought of a concrete different species.

What you'd need to identify Sphaeroceridae from pictures? Well, many setae on different parts of the body and legs, sometimes pollinosity, often also genitalia. Main problem: dark flies with dark setae leave the necessary setae indistinguishable quite often, if focus is slightly off, then it is getting neigh impossible to say much more than subfamily or group of genera.
