Only 1,5 mm, Tony!

Dear Jan
I can't see any subdivision in the "tail", so Ochtera seems unlikely. Why not Scatella or Parydra? It is not Teichomyza. Are there any prolegs?

Atylotus,
You're right: it's not subdivided. If that's necessary for Ochtera, it won't be that genus. On the other hand those 'stigmadragers' have a long base (not like in the drawing of Scatella pupa in KGV Smith) and it has some nice 'handshaped' spiracles. Looks a bit like in Scatella silacea (drawing larva KGV Smith). thanks for your help Ton

I'd agree with Scatella
