Hi Robert,

What do you think of Coremacera marginata? You can search for this species in the Forum.

I think it is Euthycera fumigata.

When I look at these two species (beautiful picture's in the diptera's database!) they look at first view quite similar to each other(to me).
Looking more specific I see Euthycera fumigata doesn't have spots on it's back and the legs are less darker and more yellowish!

Euthycera fumigata is more common in Holland I think..
Let's say rather common..


I sent a letter to Sinterklaas with some fly-lecture-wishes, I hope he will gracious to me...
In spring I will improve my pictures!Wink

Hi Paul and Andr?,

You are totally right. I was too sloppy with my suggestion. Superficially both species look similar, but there are enough differences to make clear that the fly on the picture is Euthycera fumigata instead of Coremacera marginata.
Sorry Robert for leading you in the wrong direction!

Hello!

clear that the fly on the picture is Euthycera fumigata


That leads me to the question if the fly on this picture, taken on June 9 here in Ostwestfalen/Germany, is also Euthycera fumigata? I had stored it unter Tetanocera sp., but only because I did not find a better match... Thanks in advance!

Second one may well be another Euthycera, since the spots on the sides of the frons seem small.
With long setae on antennal flagellum (the right name I hope Frown ) it may be E. chaerophylli. Short setae and two little spots on sides of frons may be E. stictica...
So.... the picture reveals too little...

Thanks, Andre! Unfortunately this is the only picture I have of this fly.

Again I disagree with Paul about Euthycera.
2. Discaused in http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=385&pid=1491#post_1491
1. I think that Jan was right and it is Coremacera. There arn't a lot of features visible. But arista is white pubescent as in case of Coremacera or Euthycera fumigata, but not black plumose as Euthycera chaerophylli. Euthycera fumigata is western species and I've never seen it, but beside general impression I have another reason: Coremacera has stripped eyes, Eu. chaerophylli - not. Robert's fly eyes are clearly stripped. I can't find any indication that Eu. fumigata (or any other Euthycera) may have stripped eyes.
