found yesterday at an edge of a forest near Marburg. Is it a female Didysmachus picipes?
Regards, Ingo

Maybe (probably), but i'd prefer to see a male... a closer look at the ovipositor could help. And a better vision of the underside of the front femora would help too.

Thank you Reinoud. I hope to find a few more individuals next week.

Now we can exclude D fuscipennis for sure. D picipes is most likely. But females are hard to id with certainty.

Nice video! The long projection on the upper forceps is visible, this has to be Didysmachus.

Reinoud, thank you very much. In my area this species seems to be related to warmer edges of forests.

In the NL the species is completely dependant on the chalkhills in the south.
