The Blue Winged Olive (BWO) of all the species and sub-species of Beatidae is one of the most varied and common insects in American rivers. There are tons of fly patterns imitating it, like the famous Adams and Pheasant Tail Nymph. A BWO in your tackle box is a must. Get ready to hook some trout with classic pattern! #flytying #flytyingjunkie #flyfishing #flyfishinglife #bluewingolive
