Ephoron leukon
white fly
Ephoron leukon, commonly known as the white fly, is a species of pale burrower mayfly in the family Polymitarcyidae. Nymphs are burrowing and inhabit tubular burrows associated with stones in river rapids, particularly in fine silt deposits. The species undergoes dramatic morphological changes during early nymphal development, including specialized mouthpart modifications for filter feeding and progressive elaboration of abdominal gills.
