Mayfly adults end up back in the water once their mating duties are lived out. They tend to have wings that are more see though and laying flat on the water's surface, while their bodies often turn a dark brown to black color. When you see these flies on the water, you'll certainly want to fish one of these spinners.
* SOLD IN BOXES OF 12.
