Predatory behavior of Proctacanthella leucopogon (Diptera: Asilidae): Prey recognition and prey records
Environmental Entomology 9 (1), 7-9
Abstract: Male and female Proctacanthella leucopogon (Williston) did not differ significantly in their attack rates toward orange and black models of a given size. Attack response for both sexes was inversely correlated with model size. Homoptera, Diptera, and Hymenoptera constituted 86% of the recorded prey items. Recorded prey lengths ranged from 1.6-13.0 mm with a mean of 4.04 mm. Diet composition and prey size characteristics are similar to those for P. leucopogon in Colorado and Mexico.
