✦ Synopsis

Feeding habits of nymphs of the predatory mayfly Dolania americana Edmunds & Traver in northwestern Florida were examined during 1971 and 1972 . Larvae of Chironomidae (Diptera) formed the bulk of prey items . The size of the predaceous D . americana nymphs was correlated with the size of chironomid prey taken. Differential microhabit utilization allows partition of prey resources with the other major predator species present. The relationship between predator and prey biomass throughout the year is discussed .
