Which Sphegina male? Hvideodde, Bornholm, Denmark, 26 June 2024. The face appears black, and the wing tips darkened. Also, the costa and subcosta seem to join before croossvein r-m. I therefore speculate towards S. nigra (syn. clavata), a species seemingly not registered that far north before.

We have after much consideration now agreed to include this observation af Sphegina nigra as a new species record for Denmark, https://www.naturbasen.dk/observation/4902959/sort-barksvirreflue One decisive character is the infuscated wing tips.
