Habitat

Visits the galls of Cynipid wasps and also feeds on flowers such as Tansy.

Life History

The ovipositor is so long that when the female Torymus bedeguaris lands on the gall, she can push it through the gall to deposit her eggs inside. When these hatch her larvae will parisitise the larvae of the cynipid wasps.
