A female jumping spider, Phidippus clarus Keyserling (Araneae; Salticidae) was discovered guarding an eggsac on herbaceous vegetation on 23 October 1997 at Clinton Lake, Douglas County, Kansas. Laboratory examination of the eggsac revealed the presence of many unhatched pupal cases of a species of tiny parasitoid wasp, later identified as Idris saitidis (Howard)(Hymenoptera; Scelionidae). The adult wasps were observed emerging from their pupal cases later the same evening. Immediately upon emergence, several matings occurred within the spider eggsac. Ten of these individuals were placed in a vial containing a recently produced eggsac of the orbweaver, Neoscona arabesca (Walckenaer) (Argiopidae). A second group of six wasps were placed in a vial with an eggsac of a funnelweb spider (Agelenopsis sp.) (Agelenidae). Oviposition was observed in neither group, and eventually spiderlings emerged from the eggsacs.
