Hymenoptera Braconidae
Braconid wasps

Hind Wings: membranous
Mouthparts: chewing
Antenna Length: shorter than body
Antenna Shape: straight
Front Legs: unmodified
Hind Legs: unmodified

Special Characteristics: Braconidae are small, usually black wasps. The abdomen is about as long as the head and thorax combined. They are usually more stout-bodied than the similar ichneumonids. Braconids are distinguished from ichneumons by a small difference in the venation of the front wing.

Comments: Braconids are parasitoids of caterpillars, sawflies and various beetles. Many species have been valuable in controlling insect pests. Some larvae are internal parasitoids while others are attached to the outside of the host's body and feed through the host cuticle. Some braconids pupate in silken cocoons attached to the outside of the host body, others spin silken cocoons entirely separate from the host.
