A wasp from the ichneumonidae family. Has one white strip per antennae, has an orange body, and a black ovipositor.
The lady beetle is still (in this case, barely) alive, clutching the pupa of the parasitoid. I've reared out parasitoids from two similar pupae, and they turned out to be Dinocampus sp. (In one case, it was identified to Dinocampus coccinellae.

The Ichneumonoidea are insects classified in the hymenopteran suborder Apocrita. The superfamily is made up of the ichneumon wasps (sometimes inaccurately called "ichneumon flies"); family Ichneumonidae and the braconids (family Braconidae). Like other parasitic wasps, they were long placed in the "Parasitica", variously considered as an infraorder or an unranked clade, but actually not a monophyletic group.
