Northern Germany, Schleswig-Holstein, Pinneberg-Waldenau near Hamburg, mixed forest Klövensteen, in a hole of an old sawed off trunk (pinetree), filled up with (rain)water, length of the larva: I think about 35 mm, moving all the time and never lost the connection to the air; 12th of April 2022. Outsidephotos: kuv.
ID possible?

I would say Syrphidae larvae but this is unknown to me. If i look in Graham Rotheray's key...Colour guide on hoverfly larvae I see some resemblance with Tropidia, with these obvious lateral lobes at the tail, but genus not sure

Sphegina also came to mind, so that is definitely als a good possibility.

Thank you very much Atylotus Smile and Iain Smile for your answers. I 'll keep "Syrphidae" and "Sphegina" in my mind in order to find perhaps more details ...
Greetings Kuv

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
