APOCRITA

Apocrita is a sub-order of the order Hymenoptera, in which the junction between the mesosoma and metasoma is clearly marked and often petiolate. The ovipositor of the female either protrudes freely or is retracted or converted into a sting for both defence and paralysing prey. The larvae are legless.
