Widows Web BWO Emerger #18

This Blue Winged Olive pattern in size #18 imitates a baetis mayfly struggling to hatch in the surface film.

BWOs hatch in cool, cloudy weather when little else is moving. Dead-drift it to rising fish during the hatch.

From MRFC, available through Madison River Fishing Company, the Ennis, Montana fly shop. A proven pattern that deserves a permanent place in your dry-fly box all season long.
