With those antennal ratios, and the dark patch on the postmentum, I'd say this was Brillia modesta or close.

Merci beaucoup. Great answer !

Brillia genera
DIAGNOSIS: Distinguished by the well developed pectinate labral lamellae; plumose S I; 4 segmented
antenna with segment 2 divided in basal third by a weakly sclerotized area; antennal blade subequal to
flagellum; distinctive mentum; posteriorly displaced setae submenti (near posterior margin of head capsule);
and procerci and anal tubules present.

As i did not have more info... I have been stopped. Brillia flavifrons impossible (different apotome and labral sclerites, different mentum)
Perhaps Brillia parva ?
in Belgium records of Brillia modesta (Meigen, 1830)
Nevertheless... Brillia is enough for my purpose.

Thanks a lot.

Apologies - I should have checked for name changes! Brillia modesta is now known as Brillia bifida. The species identification was based on Cranston's 1982 Key to the larvae of the British Orthocladiinae.

Apologies accepted Smile
Brillia names have several times been changed. Sometimes I got lost too. In the Netherlands there are 2 species of Brillia: Brillia bifida (syn. Brillia modesta) with a black gula spot and Brillia longifurca (syn. B. flavifrons). without a gula B. bifida for sure.

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.
