Overview
This PMD emerger-style nymph features a split back using thin skin or similar material to imitate the cracking nymphal shuck, with a slender abdomen often made from dyed pheasant tail or synthetic quills. The thorax is typically dubbed with a light tan or amber mix, and the pattern is weighted with a tungsten bead to get it down quickly. A great fly for technical waters and during Pale Morning Dun hatches.
