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.
