Realistic PMD Mayfly Emerger

Fly type: Mayfly emerger
Hook size: #16, #18
Pattern: Extendo
Imitation: Pale Morning Dun / PMD
Insect stage: Emerger
Primary use: Trout

The RIO Extendo in PMD is a unique forward-wing mayfly emerger for trout feeding during Pale Morning Dun hatches. Its realistic shuck/tail combination imitates an emerging mayfly caught between nymph and adult, especially when fished wet or in the surface film.

Fish it during PMD activity, over picky trout, or anytime fish are focused on emergers in slow seams, tailouts, riffles, or technical dry-fly water.
