Some pictures of (ichneumonid?) wasps, Klein Schietveld (Brasschaat), Belgium. It was rather windy, so the quality of the pictures is bad, but is it possible to get at least a genus? Thanks in advance!

Hello,

For me it Hymenoptera> Tenthredinidae and probably the genus Tenthredo for the first picture but the other two I do not see.

Best wishes Pierre

The last 2 photos seem to be Tiphia (possibly femorata) - there are 1000s in the countryside here at the moment - usually on umbellifers.

The first sawfly is probably a Tenthredo species and the second looks like Arge cyanocrocea.

1) Tenthredo arcuata/schaefferi complex
2) Arge but not cyanocrocea because of the dark abdomen

Thanks, Tony and Jorgen! On the second one: if cyanocrocea is eliminated, that leaves ochropus, pagana, ustulata, berberidis, gracilicornis, ciliaris, dimidiata, enodis, fuscipes (fuscipes), melanochra, metallica, nigripes, rustica and pullata for Belgium (dimidiata and metallica are very rare according to Waarnemingen.be). Are there more species that can be eliminated? Thanks in advance!

It's Arge rustica or ustulata, but probably ustulata.
