American Salmonfly
Pteronarcys dorsata

The adult American Salmonfly is found near the same clean streams where it developed, often resting on streamside rocks, tree trunks, and vegetation. It is a weak but capable flier, using short flights mainly to find mates and escape danger. Adults feed little or not at all compared with the long-lived aquatic nymphs, relying on stored energy from their juvenile stage. Their mass emergence can be dramatic, leaving empty nymphal skins clinging to banks and bridge supports.
