Scolia dubia haematodes
Blood-tailed Scoliid Wasp, Blue-winged Digger Wasp
Scolia dubia haematodes is a subspecies of digger wasp in the family Scoliidae. Adults are recognized by iridescent blue-black wings, black body, and reddish-brown terminal abdominal segments. Females hunt scarab beetle grubs in soil, paralyze them with a sting, and deposit eggs on the living hosts. The developing wasp larvae consume the grubs, making this taxon a significant biological control agent of turfgrass and garden pests.
