Thread subject: Diptera.info :: Strange little fly

On the 2nd. June and again on the 30th. June this year a strange little black fly came to my butterfly lamp. It was about 4 millimeters long.
I cannot even work out what genus it belongs to. The picture of the back was taken on the 2nd and the side picture was taken on the 30th.

Is it possible that this is a fly that has not developed proberly?
Has anyone a clue what it could be?
The place is Småland in southern Sweden

Grateful for any suggestions.

Best regards
Sven

I think that this is Stegana furta, Drosophilidae. Although some characters used in keys are not visible, I dont think any other north european species looks anything like this.

Head higher than wide - check!
Palpi black - check!
Legs pale - check!

Great new pictures, 100% sure its Stegana furta.

Hi Viktor,

A big thanks for your help. I would never have managed that by myself!
