Abstract

During ecological studies in 1966 and 1967, 282 scorpions of Paruroctonus boreus (Girard) were collected in can pit-traps in 12 plant communities. The ideal habitat was in vegetated areas where the total ground cover was more than 85 percent, of which at least 60 percent was broad-leaf shrubs and 5 percent grasses. Populations of ants and spiders were highest where scorpions were most abundant. Scorpions were most active above ground during August, with about half as much activity during July. None were found prior to May or after September.
