Wasp ovipositing on fungus

Postby Pristurus on 09 Dec 2014, 01:12

On 2014-07-19 I found this wasp on a fungus on a fallen beech in a forest near Marburg. A video is available here: https://commons.wikimedia.org/wiki/File:Hym_-_2014-07-19.webm. Looks for me like an Ichneumonoidea, but I've never seen one on fungus... Regards, Ingo

For me it is a Cryptinae (Ichneumonidae)

Nice video ! :wink:

I would say Orthocentrinae.

Something like that ?

But what elements here make you choose Orthocentrinae rather than Cryptinae ?

Yes, very like that!

Unfortunately the wing venation isn't clearly visible at any point in the video, however the shape of the 1st tergite and the rather small-sized propodeum are fairly distinctive.
