Thread subject: Diptera.info :: Scaeva pyrastri?

I am a bit confused of this about 10 mm long male. I can´t see hairy eyes but perhaps to unsharp picture. Signs on thoraic dorsum seems a bit odd.

But it think it is pyrastri anyway?

Thanks for your help in advance

Hey Kurt.
Looks more like a male Dasysyrphus, but I'm not sure which one.
You didn't collect it?

Thanks for your suggestion Gerard

I have had my thoughts about this a long time but can´t find any swedish Dasyrsyrpus looking like this.

I hope to get more responce on this one.

Yes, it's a bit difficult because by the angle we're looking at it it seems to have stripes on the thorax.
My best idea would be a male Dasysyrphus pinastri, looking at the spots on the abdomen.

Looking at Bartsch's Swedish Syrphinae volume, this might be D pauxillus, but almost certainly not possible to be certain from a photo.

Thanks to Gerard and Nigel for your comments
I at first thougt it vas a Dasysyrphus but did not find stripes on dorsum to fit.
