Host: tobacco hornworm (Manduca sexta
Description: This important parasitic wasp is a major factor in limiting hornworm numbers and damage, particularly late in the season. The tiny black wasp lays eggs in hornworms. Parasitized hornworms may be recognized by their shortened stubby horns. When these worms are broken open, the tiny, white parasitic larvae can be seen. When they complete their development, the parasites spin white, egg-shaped cocoons on the hornworm’s back. Parasitized hornworms damage tobacco much less and usually remain on the plant for a shorter time than normal hornworms.
