Hi, found the larva yesterday on a sallow full of Tuberolachnus salignus - Giant Willow Aphid.
I could not find a resembling one and shall be glad if you can help identifying.

I finally found out: it's a Didea fasciata.
The successful search "syrphidae tuberolachnus":
1. https://influenti..._aphid.htm
2. https://en.wikipe...a_fasciata
3. Heiss, E.M. (1938) A classification of the larvae and puparia of the Syrphidae of Illinois exclusive of aquatic forms.

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
