Hello!
I found this wingless wasp yesterday afternoon at a beech in the forest (oaks also present nearby), Ostwestfalen/Germany. Length about 5-6 mm. Could it be
Biorrhiza pallida (I find the name sometimes with two 'r', sometimes only one) from the Cypinidae (gall wasps)? Thanks!

I'm not sure if you have alternative species but it does look like a cynipid and
B.pallida would fit the bill because they are active around oaks on warmer days in winter. :)

Thanks! According to "Entomofauna germanica"
Biorhiza pallida (there spelled with only one 'r') is the only species in that genus in Germany. But I don't know, if there are similar looking wasps in related genera.

Andricus spp. are orange but they (all?) have wings as far as i know, so Biorhiza seems the most plausible. :)
