Thank you Iain.
Any suggestion to further this request.

Anyone who can help me with a key of Kowarzia species.

(Only Kowarzia bipunctata is listed so far for the Netherlands, but several others occur in neighbouring countries (source Fauna Europaea) and may be potential for our region such as K. barbatula, K. tenella, K. plectrum, K. madicola and K. tibiella.)

Hello Jan,
I suppose most species are in "Keys to the Insects of the European Part o the USSR" under the genus Clinocera. If anyone has a more recent key, I would be interested as well :-)

Just a few of the species you mentioned are in iT.
Best wishes, Niels-Jan Dek

Thank you Jan-Willem en Niels-Jan for the links and suggestions.
This gives a change to come nearer to species identification.

I wil try to check with Collins Empididae British Flies fig 314 a en c

The yellow legs and form of the surstyles may give a conclusion

I got in the meantime a copy of the page Collin 1961 fig 314 c
which is matching with the specimen and is Kowarzia bipunctata

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.

11.09.19 13:15
I’m hoping someone can identify the phoridae maggot or pupae I just uploaded.

Rafael p is legs and f1 is fore femur

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!

22.07.19 15:09
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).

16.07.19 13:31
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
