hello flyforum,

This afternoon I found this fly, sitting on a mushroom.
It got plumo arista and strange coloured part of the scutum (let's say purple shoulders)
further the apical bristels looks rather strong (that could be my (low)experience)

Is this a Suillia-fly?, and what kind of suillia?

size ~ 10 mm
place: Gaasperplas (lake near Amsterdam)

Top/bottom photos "Small to medium sized fly: yellow/dark brown/ black. Wings with small but distinctly longer, well-spaced spines mixed with the shorter spines (not visible) along the leading edge (costa); clouded".Heleomyzidae. Almost certainly Suillia sp.:p:p but nearly 50 species in this genus.

Middle photo. Same individual? Doesn't look quite right. Robert

I think so.
1+4 dc lead to Suillia.
As for species level ID you have to wait Andrzey anywait. Grace to Andrzey, I havn't real respoinsibility for my own reply, so I dare say that I think it well may be male of Suillia variegata.

Hi Robert en Nikita,

The second fly is the same fly as shown in first and last picture.
The light is different, its from another angle and a bit enlarged..(that makes the difference I think).
Is the mushroom typical in the behaviour of this flies? or is it accidental?
Thanks a lot!, Perhabs another specialist can confirm your idea Nikita.
That would be nice :p

robert heemskerk,

Hi Robert So O.K.:p The larvae of the Holarctic (Palearctic+North America)Suillinae occur principally in fungi. The mushroom fly proper is Lycoriella auripila (Diptera: Sciaridae).

Cheers Robert

Yes, Nikita is rigth !.
A classic male of Suillia variegata common in Mediterranean Basin and not rare in the Northern part of West-Europe !.
