Braconid wasp (Cotesia congregata ) on tobacco hornworm (Manduca sexta ) - 1402142

Braconid wasp
Cotesia congregata (Say)

Host: tobacco hornworm (Manduca sexta (Linnaeus))
Descriptor: Cocoon(s)
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.
