caption_attribution_description: English: Ichneumonid wasp, Hercus fontinalis, larvae (intermediate instar) on caterpillar. Size: ~ 3-4 mm. Pennypack Restoration Trust, Montgomery County, Pennsylvania, USA. https://bugguide.net/node/view/421737
context_page_description: The Tryphoninae comprise a worldwide subfamily of the parasitic wasp family Ichneumonidae.
  Most species of the Tryphoninae are koinobiont ectoparasitoids of Symphyta larvae, but members of some genera 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.
  Most species are Holarctic. Fifty-one genera are described.
