Podalonia Thread-waisted wasp  femaleAs pollinators and cutworm predators, Podalonia thread-waisted wasps are beneficial to gardeners and farmers. The appearance of male and female Podalonia thread-waisted wasps vary, with males resembling small Ammophila thread-waisted wasps and the females resembling any number of black wasps.

This solitary wasp hunts cutworms and has evolved into a design that works for carrying big payloads to feed its offspring. The female Podalonia stings its prey to paralyze it, so the food stays fresh but unable crawl away. The wasp will fly its immobilized prey to a hiding spot, like on a nearby leaf, then dig a burrow, get the cutworm and stuff it down, lay an egg on it and cover the hole. Its offspring hatches, consumes its host for weeks before gorging and killing it, and pupates underground before emerging in summer as an adult.

Adult wasps feed on flower nectar. The pictured wasp was roughly 1.5 inches long and was found feeding on the nectar of rabbitbrush flowers.
