Mike Mercer's PMD Bead Head Trigger Nymph

Mike Mercer's PMD Bead Head Trigger Nymph replicates the Pale Morning Dun mayfly nymph. The real differentiating design of this pattern is it's flashy wing case that which imitates the emerging wing case of a nymph moving to the emergent stage of it's life cycle to hatch.  This is a great pattern to throw mid summer when the PMD's are beginning to hatch and should fish extra well as a dropper under a larger dry fly.
