Overview

The Umpqua Mercury RS-2 Flashback in Gray is a sophisticated emerger pattern that excels during selective feeding conditions, especially when trout are targeting emerging mayflies or midges. Its subtle coloration and slim profile closely imitate natural insects in transition, while the flashback element adds a visual trigger that can entice even the wariest fish. Designed with a glass bead to simulate the gas bubble found on natural emergers, this fly offers realistic buoyancy and a subtle shimmer beneath the surface. Whether you're on tailwaters, spring creeks, or stillwaters, the Mercury RS-2 Flashback is a deadly choice when fish are feeding just below the surface film.

This fly is particularly effective during hatches when trout refuse traditional dry flies, as it drifts naturally in the film with lifelike motion. Its slender body and sparse profile also make it an ideal choice for pressured waters where presentation and realism are key. Used as part of a tandem nymph rig or dropped off a dry fly, it consistently delivers results when conditions demand subtlety and precision.Read More +
