SummaryOf the eight species of halictine bees whose mating behavior was studied,Augochlora pura (Augochlorini) andLasioglossum zephyrum (Halictini) were investigated in the greatest detail. HalictineExpand
Effects of weather conditions and trap types on sampling for richness and abundance of forest macrolepidoptera
In a 3-yr study (1991–1993), we compared blacklight and Townes-style Malaise traps for assessing richness and abundance of forest macrolepidoptera in 4 small watersheds in the Fernow ExperimentalExpand
