 Hello,
I found this Syrphidae larve on Picea abies. Is it possible to ID it?
Data:
22.06.2020, Germany, Bavaria, Bavarian Forest, Hoher Bogen.

Best regards
Ingrid

 Hi Ingrid, it's really nice! I've found 2 possible candidates: Parasyrphus punctulatus and Scaeva pyrastri - but unfortunately not sure. Maybe it's one assimilated to Picea abies (the stripes)

 Thank you very much Eric! :-)
But I think Scaeva pyrastri has only one stripe?

I try to breed the larva but I don't know if it will work.

 Yes, Ingrid, usually only one stripe - but I cannot find another larva of Parasyrphus punctulatus as in the "Colour Guide to Hoverfly Larvae" from Graham Rotheray (sitting on spruce needle).
Steven Falk reports "Females have been observed laying eggs on spruce but it may predate aphids on both conifers and broadleaves as it can be found some distance from conifers" here: https://www.flick...044806699/
So I hope you will succeed in breeding Mr. Hyde from Dr. Jekyll - and I'm looking forward to it!

Eric

 Unfortunately, the breeding didn't work out! Sad

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
