Abstract

Presence of a caudal appendage or tail in the last larval instar of three genera of the Porizontinae (Hymenoptera: Ichneumonidae) is reported. The structure is described and illustrated and it is suggested that it may be responsible for the jumping of cocoons known to occur in some of the species considered and not known in species that lack the tail.
