Overview

The Umpqua May Day in Callibaetis is a finely crafted dry fly that delivers a realistic and buoyant profile, making it an exceptional choice during mayfly hatches. Specifically designed to mimic the Callibaetis mayfly, this pattern is a staple for stillwater anglers and effective in slower-moving streams and lakes where these insects hatch in abundance. Its light, mottled coloring and lifelike silhouette make it a convincing choice for selective trout feeding near the surface.

The body features natural segmentation with subtle tones, while the upright wings and hackle provide excellent floatation and visibility in varied light conditions. A trailing shuck adds to its realism, mimicking a newly emerged dun or cripple. This fly excels when trout are keyed in on mayflies and ignoring attractor patterns, making it an essential fly for technical fishing scenarios. Whether used during the heart of a hatch or to prospect along calm flats, the May Day delivers lifelike presentation and consistent performance.Read More +
