Natural Habitat

Dry, sandy or open habitats, including lawns, gardens, and woodland edges. Females often roam across the ground or enter buildings accidentally.

Diet & Feeding

Adults commonly consume nectar and other plant fluids; some also take small insect prey. Larvae consume developing bees or wasps inside their nests.

Behavior Patterns

Wingless females are solitary, fast-moving, and conspicuously hairy, with a painful defensive sting. They are parasitoids: females locate host nests and lay eggs on bee or wasp larvae.

Risks & Benefits

They are not aggressive but can deliver a very painful sting if handled or stepped on; the nickname “cow killer” is exaggerated. They help regulate solitary bee and wasp populations and contribute modestly to pollination.
