Description of the Trico, Spinner, Xelon, Male - Fly:
Many of us have been baffled by rising trout that seem to ignore every pattern in the fly box. Often these selective fish are keying on spent mayflies. Trout rising to spinners often seem to sip them gently from the surface sometimes with a slight pop as they break through the surface tension from below. For selective fish use a Male Trico Spinner when they are more numerous.
