Poxyback PMD Mercer

Deceive the most selective trout in clear water with the Poxyback PMD Mercer, an elite nymph pattern engineered by legendary fly tier Mike Mercer of Redding, California. Designed specifically to target trout feeding heavily on Pale Morning Duns, this fly incorporates a brilliant drop of epoxy directly over the thorax. This signature design element flawlessly replicates the shiny, distended wingcase that natural insects develop just moments before a hatch—a critical biological trigger that predatory fish look for when feeding. Built on a premium, ultra-sharp hook with a slender, segmented body and lifelike legs, the Poxyback PMD cuts through the water column with a highly realistic profile. It is a mandatory weapon for technical tailwaters, spring creeks, and any river system where fish have plenty of time to inspect your presentation before committing to a strike. 

: During the legendary summer PMD hatches on the Grey Reef and Miracle Mile stretches of the North Platte River right here in Casper, the trout quickly grow highly educated and will reject standard, bulkier nymph patterns. The Poxyback PMD Mercer shines under these technical conditions. When fish are bulging on the surface but ignoring dry flies, they are actually targeting emerging nymphs stuck in the film. Fish this pattern on a long, light 5X fluorocarbon leader as the trailing fly in a two-nymph indicator rig, or dead-drift it directly behind a high-buoyant dry attractor like the Hi-Vis Crystal Foam Body Stimi. The reflective epoxy wingcase catches our intense high-altitude Wyoming sunlight perfectly, giving you the edge needed to fool trophy rainbows in shallow, glassy currents.
