Meteorus trachynotus (parasitoid) Viereck, 1912
This wasp is found in North America where it is an endoparasitoid of Tortricidae larvae like the spruce budworm (Choristoneura fumiferana) or the obliquebanded leafroller (C. rosaceana). It can become very common at the end of spruce budworm outbreaks.
The development goes through 3 instars and it overwinters as 1st instar larva inside its host. It emerges as prepupa from its host and spins a cocoon.
