Hello,

I am not even sure, if this is a male or female (although I would guess, a male). At the beginning of September on Heracleum sphondylium near a small creek (northwest Germany).

Hi Jürgen, I'm quite sure it's a male E. crassipennis.

Greetings, Eric

thanks! There were many E. crassipennis (see below), but this seemed to me a little bit different.

Yes, that is correct. Like in many Phasia, there are two types of males.

“macho’s”. like the last one you posted

and
“feminine”. like the first.

that came into my mind, too. Interestingly this was the only male among dozens of females that day.
