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 mesoínotum).

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