Hello,
is this the Phorocera obscura? Deciduous woodland in dunes, west of Holland (Amsterdamse Waterleidingduinen), on 10 may.
Regards, Ramon

Cyzenis.

Looks very Blondellini to me (2 prae DC, humeral bristels in a triangle).
Oswaldia muscaria comes in mind, which is pretty abundant right now.

Hmm, yeah I have to agree with Theo, just on gut feeling. Looks quite skinny and blondeliine ... I wish I saw
Oswaldia abundantly :)

Eyes are really bare this time, (? or do I lack the ability to see hairs on eyes of Cyzenis ??)

Theo´s got it right!|t
O. muscaria is the earlierst, pretty abundant here in Finland too but flies usually in June.

Took me ages to spot that
Oswaldia have the triangle of bristles on the humeral callus - it isn't mentioned when you key it in Belshaw. It makes an excellent confirmatory feature - as do the yellow halteres :)

Thanks! So this is
probably O. muscaria, or is it for sure?

If Jaakko agrees with me, it is ' beyond reasonable doubt'
as sure as it gets from picture
