Symphyta feeding on beetle

The Symphyta are known in Dutch as 'leaf wasps' (bladwespen), no doubt referring to their larval food. It was only this summer that I first saw an adult feeding on a beetle!

Wasp: Thethredinidae. Beetle: Cantharidae.

Yes, its a known behaviour in some Symphyta (esp. Tenthredo and other large species). They feed for own nutrition, because they don't care about their larva. Its difficult when collecting Symphyta together with Aculeata, because they also feed small wasp in the catching boxes.
