Alderfly
Sialis lutaria
Adult alderflies are soft-bodied, weak-flying insects found around clean ponds, streams, and other freshwater habitats. They spend much of their brief adult lives resting on waterside vegetation, mating, and laying egg masses near the water. Unlike their predatory aquatic larvae, adults feed little or may not feed at all. Their larvae can remain underwater for one or more years before emerging and transforming into winged adults.
