The Mayfly Nymph is the first stage of a Mayflies life cycle, preferring to live in silty or sand bottoms, this nymph becomes part of a trouts main food source over the next month or so. The mayflies usually last for just over a month with the abundance of them making an appearance in just one to two weeks. Keep your eye out and be prepared for when the fish turn onto them!
Attach a Kamasan B175 hook into the vice and lay a neat bed of thread onto the hook shank. Mayfly nymphs seem to move like it’s olive counterparts, in short fast darts, so adding six or seven turns of lead will help give the flies that movement your looking for. Run the thread over the lead securing it into place tapering at each edge.
At the tail, attach four or five strands of pheasant tail and cut the excess off. Then for the rib, simply tie in three extra pheasant tail strands by the tail to get a thin to thick tapering effect from the rib. Dub some tan coloured dubbing onto the thread and wind up over the lead stopping around 2/3 of the way along the hook shank. Rib the body with the pheasant tail and tie off. Add a thorax cover of pheasant tail, this time tied in with the tips facing backwards so when it’s pulled over, the excess PT will create legs.
Gently dub a lighter coloured dubbing as the thorax covering the lead right to the eye. Pull the PT over as the thorax cover and tie in. With the excess tips over the eye, carefully split the remainder evenly over each side and secure with a few turns of thread. Whip the thread off at the head and varnish.
This fly will guarantee fish when the trout are feeding on mayfly!
