Most ichneumons are smaller parasitic wasps. Most species overwinter in the cocoon as a mature larva, although some spend the winter as adult females. There may be one to 10 generations produced annually depending on the species. The larva of M. m. lunator hatch from eggs inserted into the tunnels of the pigeon tremex. Adults emerge in the spring.
Mouthparts are for chewing.
Larvae crawl along the tunnel until encountering a host larvae on which they feed. Contact your local Texas extension service agent, or search for other state extension service offices.
