Overview

The Umpqua Hunchback Infrequens is a hyper-realistic mayfly emerger pattern designed to fool even the most selective trout during technical hatch conditions. Built to imitate Ephemerella infrequens—commonly referred to as Pale Morning Duns—this pattern mimics the critical emergence phase when mayflies are most vulnerable. The “hunchback” profile represents the curved, partially-emerged body of a struggling dun breaking through the surface film, a stage that trout often key on more than fully emerged adults.

The fly’s semi-submerged profile is complemented by a high-floating wing post for visibility, making it easy to track even on slick surfaces or in low light. The realistic coloration and slender body perfectly match the natural PMD tones, while a sparse trailing shuck and upright wing add to the illusion. This pattern is ideal for tailwaters, spring creeks, and technical rivers where fish scrutinize every detail. When Pale Morning Duns are hatching and trout are refusing standard dries, the Hunchback Infrequens offers the perfect solution—blending realism, buoyancy, and just the right amount of subtle motion.Read More +
