The PMD Biot Nymph is designed to imitate the nymphal stage of Pale Morning Dun (PMD) mayflies, a prolific and important hatch on many Western and Eastern tailwaters. PMD nymphs are slim, active swimmers, and trout often key in on them heavily in the days leading up to—and during—the hatch. Using a goose biot abdomen gives this pattern its defining feature: crisp segmentation and a natural taper that closely matches the real insect. Combined with soft natural materials in the thorax and tail, the PMD Biot Nymph excels at imitating drifting and emerging nymphs in clear, technical water. This style of biot-bodied nymph has become a favorite among anglers who value realism over flash, especially when fishing pressured trout or subtle presentations. This refined material combination creates a slender, segmented profile with lifelike texture—ideal for PMD hatches and selective trout.
1. Thread base — Start the Olive Thread and wrap a smooth base to the bend of the Standard Nymph Hook.
2. Tail — Tie in a small bunch of Mallard flank, natural fibers at the bend for a short, splayed tail.
3. Body — Tie in a Goose biot, brown by the tip and wrap forward in slightly overlapping turns to two-thirds of the shank for a segmented abdomen.
4. Wingcase — Tie in a bunch of Pheasant tail fibers, natural at the front of the abdomen, tips pointing rearward.
5. Thorax — Dub a fuller thorax of Squirrel dubbing over the front third.
6. Close wingcase — Pull the pheasant tail forward over the thorax and tie down behind the eye; trim.
7. Finish — Form a neat head, whip finish, and apply head cement.
