Hi,
I tried to key out which family this is, but after several attemps I decided to ask here.

Crossveins are infuscated, not that good visible on picture ;)

Thanks in advance.

Heleomyzidae?

Hi,
I crossed this family, but I wasn't quit satisfied about it (don't really know why..)
Hope someone can confirm :)

Costal setae/spines on the wing would suggest Heleomyzidae, so one for Andrzej to ponder. So maybe change the headline to attract him to this post :)

I have changed the title.

I didn't mentioned it above, date was around 20 june 2009, in a dune area.

Dune area ! The pictures are very bad :| burt should be Trixoscelis (mesopleuron with one bristle and hairy in the upper hind area, 2 sternopleurals ! The wigs colouration indicate a species closely related to T. marginella but I'm not fully sure B)

From the coast of Belgium, are there many options other than marginella?

T. margo described by L. Papp from Hungary, if it is a bona species ;)

Hi!
I will try to make some better pictures than this.
I have 3 specimens like this, varying in size, I will post all three of them ;)

Not needed if all specimens have the same wings colouration and the same number of acrostichal rows on the mesonotum !
It would be important to know more about the wing (dorsal view of the total area) and the area between the dorsocentrals (number of acrostichals !)
Andrzej :D

This should be it :)
Number of acrostichals is not that clear on picture, but they all have 5 acrostichal bristels.
