Sherry Spinner Dry
Sherry Spinner Dry, Spinners are used to describe the female Olives when they return to water to lay their eggs. This normally happens in the evening with the females being trapped in the surface film.
You will know when this happens as it’s usually an extremely large event and you will be covered in them. In this instance, there is no other option than a spinner and its quite a difficult hatch to catch in despite trout being in a feeding frenzy state.
