Insect of the Week (July 3) - Aphidius parasitoid wasp

This week's Insect of the Week is the Aphidius parasitoid wasp. Their hosts include over 40 species of aphids. Egg to adult development occurs inside the host. New adults chew a hole in the mummified aphid to exit and immediately search for new aphid hosts.

For more information on the Aphidius parasitoid wasp, see our Insect of the Week page.
