GENERAL INFORMATION
for Cotesia ruficrus

Description: A parasitic wasp that can be used for the biocontrol of various caterpillars

Appearance and life cycle: Adults are small (2-3mm), dark wasps and resemble flying ants or tiny flies. They have two pairs of wings. Larvae occur in an irregular mass of yellow silken cocoons attached to the host larva or to plant leaves. Eggs are laid inside host larvae which then hatch and feed upon the host. Larvae emerge to spin cocoons on or near the dead host.
