Braconid wasps

This large family of wasps contains many important parasites of pest insects. Different wasp species attack particular insect stages. Eggs are laid inside the host. The larvae of some species develop inside the host, and some develop externally, creating small oval, white cocoons on the outside of the host’s body.

Adult wasps are < 10 mm long, black, orange or yellow in color. This braconid wasp is parasitizing codling moth eggs.
