Hi all, and especially Theo, of course!

I'm struggling here with bimaculata and arpadi... The key tells me, if unsure with the palps, look at the hind margins of the tergites. If noticeable pale, it's arpadi. They are, I think, but I'm still in doubt. Also the mostly orange antenna seems to give me a hint towards arpadi. Orange hair at the abdomen... for bimaculata ok, I think, the black ones of apadi are missing. So what is ist now?

About 15 mm.

Thanks Theo!

Almost exclusively yellow hairs, that's it... Failed again. Too well hidden between all the bimaculatas. Wink I will learn it.

Btw thanks for making this great book! It' in daily use for many weeks now.
