Diet & Feeding

Adults feed on nectar from flowers. Larvae are carnivorous and feed exclusively on spiders provided by the mother.

Behavior Patterns

Solitary insects known for hunting spiders. A female stings a spider to paralyze it, drags it to a burrow, and lays a single egg on it before sealing the nest.

Risks & Benefits

They provide a benefit to the ecosystem by controlling spider populations. While they are usually not aggressive toward humans, they have a very painful sting if handled or provoked.
