Hello!

This rather big (ca. 20 mm) Ichneumonid ran around our wintergarden wall (under a cherry tree, from which the pollen may come from) in the night last Saturday northwest Germany).

Definitely Ichneumonidae but not sure which

@BubikolRamios - check the length of the antennae - too long for Sphecidae ;)

Hello!

Thanks. I was rather sure about Ichneumonidae. And we don't have so many true Sphecidae (not Crabronidae) here. I only saw a Sphecid once in my lifetime here: Ammophila sabulosa.

I was looking at second image for comarison to this one here.

The antennae may be relatively long, but they only have 12-13 segments. In Ichneumonidae there are at least 16 much smaller segments (mostly many more). I'm not able to count the segments at this animal (too blurred in the dark sections), but there are in any case more than 13.

Exactly :)

I am not an expert, but your animal is overwintering fertilised female of Diphyus palliatorius or any extremely similar species.

Thank you! I had a male identified as that species already in August-09:

Many thanks, Camille!
