Adults feed primarily on nectar, pollen, or honeydew. Larvae are parasitic, feeding on the body fluids and tissues of other insects and spiders.

Behavior Patterns

Females use their long antennae to locate hosts hidden beneath bark or soil and use their long ovipositor to deposit eggs inside or on the host.
