Methocha
Methocha is a genus of parasitoid wasps in the family Thynnidae (formerly Tiphiidae) that specialize in attacking tiger beetle larvae. Females are wingless and exhibit striking ant-like morphology and behavior, while males are winged. The genus shows pronounced sexual dimorphism and has been documented engaging in remarkable aggressive predatory tactics to access its hosts.
Polytribax
Polytribax is a genus of ichneumonid wasps in the subfamily Cryptinae containing approximately 15 described species. Members are parasitoids of Lepidoptera pupae, with females adapted for ground-level foraging in leaf litter and soil. The genus exhibits strong sexual dimorphism, particularly pronounced in Polytribax perspicillator. Species are distributed across the Western Palaearctic with records extending to the Oriental and Nearctic realms.
