(John Obermeyer, Purdue University)
Common Name: Caddisfly

Order: Trichoptera

Family: Limnephilidae

Pest Status: Caddisflies spend the majority of their life as immatures in aquatic habitats where they are an important source of food for fish.

Appearance: Adults are small (1/4-inch or less), dull-colored and have long hair-like antennae. Caddisflies hold their wings tent-like over their back when at rest.

Life Cycle: A female lays her eggs on the edge of a body of water. Larvae develop over several months. Some species form and live in cases of sticks, sand grains, twigs, or other materials.

Where to Collect: Caddisflies are abundant near cool, fresh water habitats. Adults are usually nocturnal.
