 Hi

Switzerland, Kanton Schwyz, Altendorf (near lake Zurich), 430m, 23.07.2025

Could this be a Paragus haemorrhous? Female? Comparing pics in the gallery, I found pure black ones.

Thanks a lot, kind regards
Brigitte

 Hi Eric

I should have seen that it is a male.
Thank you for the information and for mentioning the species complex.

Kind regards,
Brigitte
