Pepsis grossa
Pepsis grossaAlso known as Tarantula Hawk, Tarantula Hawk Wasp, Tarantula Wasp
Tarantula hawk wasps are famous for their metallic blue-black bodies and contrasting bright orange or dark wings. Females hunt large ground spiders, paralyzing them with a swift sting before dragging them into burrows to feed a single developing larva. Adults spend their days feeding peacefully on flower nectar and fermented fruit juices.
