I took this picture in Jura region (Northern Switzerland, alt: ~700m) of that beetle (July 2018). It was taking food from a flower of a Morus nigra.

trichius-up trichius-front

It seems to be part of the trichius genus but I want to report the exact species.

In Switzerland we have mainly:

  • Trichius fasciatus
  • Trichius rosaceus
  • Trichius sexualis

I think by the color of the hairs it would be a Trichius fasciatus.

Can someone confirm the species and what field marks I can use to make the distinction between those three species?
