Fishflies (Megaloptera: Corydalidae: Chauliodes sp.) can be found throughout eastern North America wherever there are slow-moving rivers and floodplains. Their juvenile aquatic nymphs are omnivores, feeding on the decaying plant matter and small arthropods that litter these waters. After fattening up the nymphs pupate in rotting bark or logs, emerging only about ten days later as adults.

Mature fishflies can reach nearly two inches (5 cm) in length, and although they look a bit frightening most never eat or even bite. They live for only a week or less, spending their limited lives as adults trying to mate rather than feed. Once females have been impregnated, they lay their eggs near the waters from which they emerged and then die, leaving the calm waters to their offspring.
