In early summer damsel fly nymphs become an extremely important food source for bass and panfish. Mihulka's Damsel Nymph is a really effective fly to imitate this fish favorite. Try this nymph on a dropper tied below a popper just like trout fishing a hopper/dropper rig. Reed beds are a favorite place to find active damsel fly nymphs in lake and ponds. Match the hatch for large panfish and bass too.
