Stylopidae is a family of twisted-winged insects in the order Strepsiptera.

[4] Stylopidae are associated primarily with wasps and bees[3] but are known to also use members of Blattodea, Mantodea, Orthoptera, Hemiptera, Diptera, and other Hymenoptera as hosts.

[5] As with others in the order Strepsiptera, Stylopidae larvae called triungulins enter their host and develop inside it.

Females draw males with pheromones who mate with them by means of the exposed brood canal.

The eggs will hatch inside of their mother, and the larvae will feed on her body until it is time for them to exit through the brood canal and find their own hosts.
