Morris May Emerger - Bwo is a purpose-built mayfly emerger pattern engineered for tough trout. This mayfly emerger pattern mimics a vulnerable nymph wriggling from the shuck at the surface, with the nymph-half staying submerged as the front half rides the surface. The design recreates the moment the thorax frees from the shuck, producing a natural, enticing drift. Field-tested across Colorado, Montana, Idaho, Washington, Oregon, and British Columbia, it consistently triggers takes in challenging currents. Ideal in riffles and seams, it maintains a readable profile through water.

Compared with typical half-sunk emerger flies, Morris Emergers float longer and stay on the surface as stubborn floaters even in swift water. The design reduces downstream drag and premature sinking, delivering a steadier drift through current.

• Front half floats while the nymph-half stays submerged
• Longer floating than typical half-sunk emerger flies
• Designed to resist downstream drag and premature sinking
• Effective mayfly emerger pattern for trout in swift current with extended drift
• Field-tested across Colorado, Montana, Idaho, Washington, Oregon, and British Columbia
