The Headlight Caddis fly incorporates a calf body post that makes it very visible and a CDC under wing that keeps it riding high in the water.
Adult caddis live significantly longer winged lives than mayflies and will spend up to two or three full weeks away from the water. When they’re finally ready to mate, males will gather near their home water to form a swarm. Females will join the swarm to have their eggs fertilized. Once the mating process has been successfully completed, females will deposit their eggs on the water’s surface, propagating the species.
