Olive Foam Case Spinner

Olive Foam Case Spinner is a dry fly representing an adult mayfly in the spinner stage—the spent insect lying on the surface after the hatch. Its foam body helps keep it floating. Use it in the evening, when trout and grayling are taking spinners from glides and slow runs.

Present it on a drag-free drift without retrieving it. Choose size #12 for larger insects and #18 for smaller ones. The barbless hook makes releasing fish easier.
