Life History

Nymphs of this species live in pools and margins of rivers and streams where they swim in short, darting bursts amongst the substrate, or climb amongst the vegetation. They feed by scraping algae from submerged stones and other structures, or by gathering or collecting fine particulate organic detritus from the sediment.
