The little Blue Winged Olive (BWO) mayfly of the family baetidae are arguably the most important moving-water mayfly hatch for both the trout and the fly angler. Capable of producing two generations per year, the BWO's high level of activity both as a nymph and as an adult make it both available and vulnerable to feeding trout. While patterns such as the RSII, Barr's Emerger, and Greg's Emerger can be used to imitate the wet emerger, the BWO Parachute Emerger seeks to bridge the gap between both the aquatic and terrestrial worlds. Half-submerged yet still considered a dry fly, this pattern can be used to imitate both the emerging dun and crippled BWO.
