Occurrence of Parasitoid Wasps, Baeus sp. and Gelis sp., in the Egg Sacs of the Wolf Spiders Pardosa moesta and Pardosa sternalis (Araneae, Lycosidae) in Southeastern Idaho

Abstract

Egg sacs of the wolf spiders Pardosa moesta and Pardosa sternalis were sampled for two years during June to September in southeastern Idaho. Parasitoid wasps, Baeus sp. (Sceleonidae) and Gelis sp. (Ichneumonidae), were observed in the egg sacs of both Pardosa species. Of 322 egg sacs examined, 14.6% were parasitized. Parasitism of egg sacs occurred throughout most of the Pardosa egg sac-carrying season.
