Most species of the Tryphoninae are koinobiont ectoparasitoids of Symphyta larvae, but members of some genera (e.g. Netelia) are ectoparasitoids of Lepidoptera larvae. Tryphonines have a hair-margined clypeus and two longitudinal parallel ridges occur on the first tergite. The female sometimes has stalked eggs projecting from her ovipositor.
