Just the family would be a help please, so I know whether to attempt an id.

Cecidomyiidae. Five species are recorded from Lipara galls in Nartshuk and Andersson (Frit Flies of Fennoscandia and Denmark) see https://books.goo...mp;f=false

Many thanks. I hope we have a cecidomyiid expert on Diptera.info.

I think it belongs to supertribe Lasiopteridi.

Thank you. Of the species listed in Fauna Ent Scand (see Tony Irwin's reply above), the only Lasiopteridi on the British list is Lasioptera arundinis. But I'm not sure that is strong enough evidence to say my specimen is L. arundinis.

It is not Lasioptera because vein R5 reaches to near wingtip.

Thanks. So it is likely to be a species not recorded previously from Lipara galls.
