Hi forum,

Found this today on a dead treetrunk. Fagus sylvatica => beech.

Austria, Vienna. 24. April 2022.

S. hypoleuca. To my knowledge, reported from Vienna (and Austria) previously only in a 1848 paper. Can you mention the dimensions (length) of the fly?

7-8 mm. First I thought it was a beetle.

This supports the identification (S. hypoleuca is much larger than other European Stegana spp. with pale mesoĆ­notum).

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
