The adult wasp is black, slender and about 1/4- inch long but is rarely recognized in the field. The female lays an egg beneath the skin of a small budworm. The egg hatches and larva develops inside the budworm. When development is complete, the parasitic larvae emerges and pupates outside attached to a tobacco leaf. The silken cocoon is white, oblong, and about 1/4 inch long and is frequently attached to the skin of the host budworm. This parasite may kill 70% to 80% of the budworms in a field.
