Aphid Parasitoids

Insect

Adults are black, 3-8 mm in length, stout-bodied wasps with long antennae. They lay individual eggs within aphids. Parasitized aphids are referred to as ’mummies’ and appear white or tan, swollen and papery, and remain attached to the leaf. The wasp takes one week to mature and then cuts a small hole in the shell and emerges as an adult.

Role

Biological control of aphids.
