Spilichneumon
Spilichneumon is a genus of ichneumon wasps containing at least 30 described species. These wasps are notable for being among the first wasps active in early spring, having overwintered as adults in protected locations such as rotten logs. The genus has a holarctic and Oriental distribution, with North American species concentrated in northern regions, Canada, Alaska, and mountainous areas extending south to Arizona. Females are internal parasitoids of noctuid moth caterpillars, with larvae developing inside hosts and emerging from the pupal stage.
