Eruga
Eruga is a genus of ichneumon wasps in the tribe Ephialtini, comprising approximately 15 species distributed across the Afrotropical, Nearctic, and Neotropical regions. Members of this genus are ectoparasitoids of spiders, specifically targeting species in the families Linyphiidae and Tetragnathidae. The genus is notable for behavioral manipulation of host spiders, inducing them to construct modified 'cocoon webs' that support and protect the wasp's pupal cocoon.
