Behavioral observations on both sexes of three parasite members of a Spondias bark community are presented. A small scolytid beetle, Styphlosoma granulatum Blandf., served as host for two parasitic wasps, Theocolaxia pityophthori (Ashmead) (Pteromalidae) and Ecphylus costaricensis n. sp. (Braconidae). Searching and courtship of a third wasp, Pedinotus columbianus Enderlein (Braconidae), whose host was undetermined, are also described. Accidental parasite-ant encounters were surprisingly frequent, and their possible impact on the evolution of the wasps\&$\#$39; behavior is considered.
