Abstract:

From June 1966 to September 1967, approximately 500 spiders representing 42 species in 31 genera were collected in can pit-traps at the National Reactor Testing Station in Idaho. Four of the species are new to science. The greatest variety of species was found in study area 10 where the vegetation analysis was 68% Artemisia, 7% Opuntia, 7% mixed grasses, and 5% miscellaneous forbs. The fewest numbers of species were found in study areas 7 and 11, typified predominantly by Chrysothamnus plants. Males of all species of spiders combined were collected from April to November. Greatest numbers were found in October. Females of all species were taken from April to November, with slightly more in October than in other months. Immature spiders also were found from April to November, with greatest numbers occurring in August, October, and November. The species that were the most widespread over the station are Schizocosa avida and Calilena restricta. The most abundant species was S. avida; Tarentula kochi was only half as abundant as S. avida, but twice as common as any other species
