In his latest podcast,Tom Rosenbauer talks about spinner falls and why the frenzied feeding of trout on spent spinners makes fishing a classic “hatch” seem dull in comparison. “Mayflies live underwater for just about 12 months. Then the nymphs rise to the surface, they split their skin, and an immature adult emerges from the skin. It’s a winged adult, but it’s actually not a true adult because they’re not sexually mature yet. This is called a ‘dun,’ or subimago, and the dun is kind of an intermediate adult stage. And this is what people refer to when they talk about a ‘hatch.'”
