Larval cannibalism, time constraints, and adult fitness in caddisflies that inhabit temporary wetlands

Abstract

The fitness of non-feeding adult insects depends on energy accumulated during the larval stage. Larvae of the caddisfly Asynarchus nigriculus primarily feed on plant detritus, but supplement their diet with animal material obtained through cannibalism. Habitat drying constrains development in many populations of this species, and we hypothesized that… (More)
