Order & Family
Hymenoptera: Sphecidae
Size
15 to 25 mm (0.6 to 1 inch)
See this bug in the Encyclopedia

Natural Habitat

Open fields, gardens, pastures, and sandy areas suitable for digging burrows

Diet & Feeding

Adults feed on flower nectar. Females hunt katydids and grasshoppers to paralyze and stock underground burrows for their larvae.

Behavior Patterns

Solitary, ground-nesting thread-waisted wasps. Females dig tunnels in sandy soil with multiple cells, provisioning each cell with paralyzed orthopterans before laying an egg inside.

Risks & Benefits

Non-aggressive towards humans and rarely sting unless directly handled. They serve as beneficial native pollinators and help control pest populations of katydids and grasshoppers.
