identification of Chysotoxum spp is a lot more challenging than I thought.

Thx for everyone.
I expected a minimum of 3 species, but I hoped for up to five. I tried to key out many of these, but I usually could narrow down the id to a couple of species. The Chrysotoxum key does not work well with photos.
Nr. 9 was in my opinion clearly going to lay eggs. It was crawling on the ground among fallen leaves and grass in early spring with an exposed ovipositor. This would not be surprising as the larvae are supposed to feed on root aphids based on van Veen.
