Blue Winged Olive Parachute

This month's fly is the Blue Winged Olive Parachute. The small B.W.O. is the first bug to hatch in the spring. It only requires water temps in the 45 degree range to begin hatching. The hatch often occurs during cloudy weather which keeps the bugs from drying and flying, making them vulnerable to feeding trout.  The parachute design also can make the fly look like a spent or crippled insect.
