Umpqua RS Dragon Fly Nymph Dark Brown, a very good nymph fly for trout for almost all season.
A very effective imitation of a dragonfly nymph. This pattern is very good in still water almost all season long, with a peak on spring and presummer.
Moisten the fly well before using it and you can also use TMC Sink Gel to make it break the surface easier and sink faster. The pattern is made to be fished on shallow water so it's weighted perfectly. It's small spandex legs are very robust and lasts longer than regular rubber legs. The pattern is designed by Rune Andre Stokkebekk.
A very good fly for trout in small lakes.
