Blue Winged Olive
Hook Size: 16
Season: June to August
Natural Fly: Blue Winged Olive (Baetidae)
Time: Mid-Afternoon / Evening
Where: Slow Water
Tips: Search out back-eddies on the river. This is where anglers normally find blue-winged olive circling endlessly around and around. This fly also works well in slow run stretches of water. Use your eyes and hunt the swarms. Look out for airborne insect eating birds like swallows feasting on or near the water surface.
