The life history of this genus is known quite well, since the larvae are endoparasites of Ladybird Beetles (Coccinellidae) and these beetles are of economic imprtance. The adults are typically found on tree trunks.

I saw them buggin the pupae of Harmonia axyridis the multicoloured ladybird and they even seemed to attack a prepupae. I will see if I can find more about these parasites, or do you happen to know weblinks or literature? Thanks, elck PS I saw that our own Paul wrote about these flies on a begium forum, I hope he can tell us more!
