I have difficulties to identify this caterpillar and aphids.
They are on a cruciferous plant (austrian cress, Rorippa austriaca) in Germany, Tübingen.
For the caterpillar: I excluded specialists from cruciferous plants and expect it to be a generalist.
For the aphids: I am a bit lost since there are some who are black and some who are green. It could be two species with the black ones being Aphis fabae. The green ones have short antannae which seems weird and often excludes aphids that I thought it could be.
If someone has an idea, I would be happy to hear them :)
