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.
Hydropsyche bronta
A net-spinning caddisfly species in the family Hydropsychidae. In summer-warm rivers of southern Ontario, populations exhibit trivoltine life cycles, completing three generations per year. Smaller than the sympatric H. morosa and overwinters in slightly older larval instars.
