Have a Caddisfly Problem?

Description

The Caddisfly is a small, winged insect that lives and breeds near freshwater streams and lakes. The Caddisfly is closely related to butterflies and moths and may be mistaken for a moth. Adults have two pair of wings and a pair of antennae that can be twice the length of the body.

The female Caddisfly will lay eggs or next to fresh water where they remain until the larvae hatch. The larvae remain underwater until they emerge as adults. Newly hatched adults often swarm close enough to the water that fish can eat them. The Caddisfly is a favorite lure of fisherman as bait for trout.

The Caddisfly is attracted to bright lights and the adults may become a nuisance when they swarm to lights at night.
