What is a fish fly?

Fishflies are insects in the family Corydalidae, closely related to dobsonflies. Here's some information about them:

• Appearance: Adult Fishflies are typically brown or grey, often mottled, and can range in size from 1 to 3 inches long. They have long antennae and large, net-veined wings that they hold tent-like over their bodies when at rest. Males often possess elongated mandibles, although these are less dramatically developed than those of male dobsonflies.

• Habitat: Fishfly larvae are aquatic and found in streams, rivers, and ponds, usually in areas with rocky or sandy substrates. Adult fishflies are typically found near the aquatic habitats where they developed.

• Life Cycle: The Life%20Cycle of a fishfly begins with eggs laid near water. The aquatic larvae are predators, feeding on other insects and small invertebrates. Larvae can spend several years in the water before pupating in the soil near the water's edge. The adult stage is relatively short-lived, with adults primarily focused on reproduction.

• Diet: As larvae, fishflies are carnivorous, preying on other aquatic insects, crustaceans, and small fish. Adult fishflies do not feed extensively and may only consume nectar or other liquids for energy.

• Behavior: Fishfly larvae are nocturnal hunters. The adults are often attracted to lights at night. Although they can appear intimidating due to their size, they are generally harmless to humans.

• Distinguishing from Dobsonflies: Fishflies are often confused with Dobsonflies, but there are a few key differences. Fishflies are generally smaller and less robust than dobsonflies. Male fishflies have less exaggerated mandibles than male dobsonflies. Fishfly wings also lack the dark markings often found on dobsonfly wings.
