Brown Dun Nymph

The Perfect Fly Brown Dun nymph is a trout fly that imitates the Brown Dun mayfly in the nymphal stage of life. Brown Dun nymphs are little swimming nymphs. They can’t actually swim but dart about on the bottom and should be fished on or near the bottom.

These nymphs are excellent swimmers. Like some of the other swimmers, these nymphs migrate to the shoreline and emerge into duns If you intend to fish the shoreline during a hatch the key is determining when the migration is occurring. This does concentrate the nymphs somewhat and increases your odds of success. Otherwise, fish the normal places nymphs may be found within the stream such as pools, pockets, runs and riffles. Presentation: Fish the nymph in the fast water up until the time they are ready to emerge. You can use a deep dead drift, on the swing or a strike indicator. When the nymphs move into shallow water to emerge, use a slighted weighted imitation or small split shot with an upstream approach. Copyright 2003 James Marsh
