Although not as important to anglers as the nymph, there are times when an adult damselfly pattern can be very effective. If there are a lot of adults damselflies present, and especially if there is some wind on the water, it is definitely worth trying. Often times, trout will jump out of the water in an attempt to capture low flying adults, or bump tules to dislodge resting "tenerals" (newly hatched adults).

It is most commonly fished with a cast and let sit style, with occaisional twitches mixed in. But, I have also had success by retrieveing this pattern, slow or fast (damsel in distress?).

This fly can be tied in tan, blue, or olive/tan. In most cases - tenerals male or female) are olive/tan or tan, mature females are tan, and mature males are blue.
