From midwest Sweden 2006-JUL-02. This is not a good photo. My hope is that there are no other species that look and move like this one. It was moving constantly while swaying it's flashy antennas. Which the photo actually shows pretty well.

To turn non-Diptera threads into Diptera I can add Thai Micropezidae who mimic Hymenoptera antennae perpetualy moving thier forelegs.
It is genus Mimegrella. Species level ID in progress...

For me, the first picture is a female Symphyta.

Tentrhedinidae and Ichneumonidae can look quite similar, but the Ichneumonidae wasps usually have the white part of the antennae subterminally, while in Tenthredinidae it is terminal.

Thanx for all help. I think it is a Tenthredinidae species, as suggested. I didn't think this kind of look was common, and looking through a bunch of Tenthredinidae photos there aren't that many showing these antennas, but on the other hand there are a lot of species in this family - 480 in Sweden!

Interesting to see Mimegrella mimicing long antennas with front legs ...
