Subfamily Anomaloninae contains more than 700 species found in every region of the world except the Arctic and Antarctic.
Members of tribe Gravenhorstiini are koinobiont parasitoids, that is, parasitoids whose hosts continue their development despite being parasitized. The hosts are caterpillars of several families including Saturniidae and Lasiocampidae (Shimizu 2019).
Some wasps in this tribe attack agricultural pests (Quicke 2015).
