Overview

The Umpqua Jiggy Micro May is a precision-tied Euro-style nymph that brings modern performance to a classic small-profile fly. Based on the legendary Micro Mayfly pattern, this jigged version is tied on a barbless hook with a tungsten bead to ensure rapid sink rate and snag-resistant drifts. Its slender, segmented body mimics small mayfly nymphs—particularly Blue-Winged Olives—and other tiny aquatic insects that make up a major part of a trout's diet in clear, technical water.

The jig hook keeps the fly riding point-up to reduce snags and enhance hook-up ratios, while the slim, realistic build and subtle flash ribbing help this pattern trigger takes in both bright and low-light conditions. Whether used as a dropper behind a larger fly or fished solo on a Euro-nymphing rig, the Jiggy Micro May delivers consistent results. It's especially effective during spring and fall BWO hatches, and it's a go-to option for targeting pressured or selective fish in tailwaters, spring creeks, and clear freestones.Read More +
