Brief Summary
provided by Catalog of Hymenoptera in America North of Mexico
The members of this medium sized subfamily are internal ED. parasites of Diptera larvae. The eggs are deposited in the early-instar larvae or eggs of the host, and the adults emerge from the host puparia. The usual hosts are aphidophagous Syrphidae, although phytophagous Syrphidae and even Diptera of other families are sometimes parasitized.
