Good afternoon,

here are three pictures of Tenthredinidae with the request for identification help. Body length about 7 mm. Habitat sandy dry grassland in southwest Germany. The pictures were taken in April 2022.

Thanks for the help.

Hi Bembix, I think it's a Dolerus sp. but I cannot proceed further to species level.

Dolerus species have only three cubital cells, in the second picture we can clearly see four. I think this belongs in the subfamily Blennocampinae.

Hence I couldn't find a matching Dolerus! Thanks Arthur!
