....................... ......Fly Fishing Yellowstone National Park
New "Perfect Fly" Damselfly Nymph
The Damselfly is a stillwater insect that is also found in streams with slow moving water. The insects prefer water with lots of vegetation. That is where they hide to catch the food they eat. The Madison, Firehole, Gibbon, Yellowstone, Bechler and other rivers in Yellowstone National Park have these insects as well as all the lakes.
The best time to fish imitations of the nymph is just prior to or during a hatch. When the nymphs begin to hatch into an adult they swim to the shore beneath the surface of the water. They usually swim within a few inches of the surface, not in the deeper water. That is what you want to try to imitate during a hatch.
Nymph Presentation: You can also fish imitations of the Damselfly nymphs anytime of the season. You should present the fly in and around the shoreline vegetation. In some cases, depending on the level of vegetation in the stream, you may be able to work the nymph over submerged weed beds or grass beds.
It is best to add some action to the fly by slowing stripping it in with twitches of the line. A slight flicker of the tip of the rod also seems to help add a swimming action to the fly. The "Perfect Fly" Damselfly Nymph has a lot of built-in action but it may help to add to it during the retrieve.
