About 1,000 species of Agathidinae have been described; the subfamily is found in many regions of the world.
Females lay eggs in caterpillars, and the wasp larvae grow while the caterpillar develops. The ovipositor is usually long, and is often used to probe places where the caterpillars are hidden (Hanson and Gauld, 2006).
