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 .. Shock

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

Inconclusive previous discussion here on the wrn-forum.

Only the one more or less "usable" image

Thanks in advance!

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.
Best regards,

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 ? Frown

Thanks for the explanation Paul. It definitely stopped me from flooding the forum with my threads Wink

Each user has a maximum of ten new threads per day (24 hours). Just to prevent a single user from sending scores of his unidentified fly photos at once and thus drain out any other threads.

Hello, I'm having a problem posting new threads, as the "No new Threads allowed..." is showing up on all of the forums. Is there some sort of thread limit I've exceeded?

SabineH: you have to be logged in to see "New Thread" in the right upper corner of each "forum" site. In the case of accidental logout you have to start over.
