Natural Habitat

Arid regions, deserts, and shrublands; commonly found from the Southwestern US down through South America.

Diet & Feeding

Adults feed on nectar from flowers; larvae are parasitic and feed on tarantulas paralyzed by the mother wasp.

Behavior Patterns

Solitary hunters; females capture tarantulas, paralyze them with a sting, drag them to a burrow, and lay a single egg on the spider. They are known for their striking aposematic coloration (blue-black bodies with bright orange wings).

Risks & Benefits

Possesses one of the most painful stings in the insect world (Schmidt sting pain index 4.0), though they are generally non-aggressive toward humans. They benefit the ecosystem as pollinators and by controlling spider populations.
