Should be Psocoptera.
Cheers, Helge

Hi Helge,
it looks a little like Psocoptera but the size does not fit. As far as I know Psocoptera are 3-5 (-10) mm in size and this one was larger.
Unfortunately I have no exact size but by comparing it to the bark it was rather 10-15 mm.
Regards Lars

Hello Lars,

it is Psocoptera.

Unfortunately I have no exact size but by comparing it to the bark it was rather 10-15 mm.

The biggest european Psocoptera, Psococerastis gibbosa reaches a wing span up to 16 mm and a body length of 7-7.5 mm.
This is not Psococerastis, but another rather big species, maybe Metylophorus nebulosus (body length 6-7 mm). Compare here:

Hello Jürgen,
I agree. So my size estimate was mistaken.
Thanks for the link. My best guess from this list would be Metylophorus nebulosus. Correct?

Sorry you suggested Metylophorus nebulosus. So I agree.

Jewell699, you should post it in the forum, not submit it for the gallery.

15.09.19 20:41
Jewelm699 - did you upload it to a forum (which one?) or the gallery? I can't find it.

I’m hoping someone can identify the phoridae maggot or pupae I just uploaded.

If you experienced a very sluggish site recently, it may have been because someone tried to upload a maliciuous script by force. It appears to have failed. The visitor was blocked further access.

@Paul Beuk Thanks mate!! Best wishes!

Where are the meaning abbreviations of Lindner's series Die Fliegen der Palaearktischen Region, ie. f1: anterior femur, ...and what about "p"? (I don't possess volume I)

17.07.19 19:37
Yup, you can view the wing from above (dorsal side) and from beneath (ventral side).

Hey Dipterists! Quick Question: Vein r2+3 bare beneath. I've always assumed that this is below as in when you look at the wing flat. Am I right? Thank youuuuu! Pfft
