Planidia of the hyperparasitic wasp, Perilarnpris similis Crawford, enter their braconid host, Agathis rnetzneriae Muesebeck, during that host's active growth phase, returning to the outer surface when the host is prepupal. Second instar perilampids search for and destroy conspecific larvae on the surface of the braconid prepupae, thus eliminating super- parasitism. Planidia in primary hosts, Metzneria lappella Zeller moth larvae in burdock seeds, unparasitized by the braconid persist without further development through pupation and occur in various tissues of the adult moth.
