Dear fly specialist,
Long time since my last visit. Normally don't shoot flies anymore because the ID just takes me too much time. Made a "mistake" last Saturday and thought "what the heck, let's give it try again"... silly me .. :o
Okay, I've landed at
Helina impuncta female but obviously the photo is not showing all the details used in the keys (too bad to really tell) ... so, any specialist who dears to ID this "on jizz" or some other gut feeling?
Observation data
here on waarneming.nl
Inconclusive previous discussion
here on the wrn-forum.
Only the one more or less "usable" image
Thanks in advance!
Cheers,
Arp

No opinions so far ...
Should I forget about the species name and leave it at
Helina sp. ?
Or is
Helina cf. impuncta a fair shot?
What are the other options in the Netherlands ?
Thanks in advance fir any pointers!
Cheers, Arp

Hello Arp,

since no one of the experts replies... I would say, this is
Helina impuncta or
depuncta. I don't know, whether there are more, rarer similar species.

Hi Jürgen,
thank you for your answer! I had ruled out
depuncta due to this specimen having 4 dorso centrals.
From what I had found, impuncta can have 4 or sometimes 3 (giving cause for confusion), but depuncta never 4. But my info may be wrong (?!?) I don't own much literature about flies.
My uncertainty would be about maybe other species with pale legs such as maybe
sexmaculata, but probably also others without images in the gallery here ? :|
