Abstract

Aquatic insects have numerous adaptations reflecting the coevolution of predators and prey. Predators have a wide variety of search, capture, and consumption mechanisms, and prey demonstrate various physical, chemical, and behavioral defenses. Mortality in prey populations from predation may be significant. Although most aquatic insect predators are opportunists, certain prey sizes or types may be preferred, suggesting predator influence on prey community structure.
