Pelecinid Wasp - Pelecinus polyturator
Females are distinctive: their abdomens are five times the length of the rest of their body. The abdomen has six segments. Males are rarely seen in temperate areas, and this species is suspected of being capable of parthenogenesis.
They do not sting. The female uses her long ovipositor to penetrate the soil in search of scarab beetle grubs to lay her eggs on/in.
Habitat: Mixed, mostly coniferous forest. She was resting on my tent and had no interest in moving. I left her there and found her in nearly the same spot the next morning. I finally had to move her to a nearby tree.
'Pelecinus polyturator' is a large glossy black wasp, the most common and familiar species in the family Pelecinidae. The adults drink nectar. They live in crop fields, woods, and suburban gardens throughout North, Central, and South America. Their antennae are long and the females have an elongated, cylindrical, articulated metasoma. They are parasitoids that lay their eggs directly into grubs of the June beetle buried in the soil. The adults can be found in the late summer.
