Sunken Trico Spinner

Any good mayfly hatch leaves a lot of spent spinners on the water after they have mated and laid eggs. The trico is one of the biggest hatches in the late summer on the Bighorn River. After these adults hit the water, they eventually sink, giving the trout an abundance of food. Once the fish stop feeding on the surface, a trico spinner can be effective for hours after a thick hatch.
