Someone tell me (with understandable words) exactly what a mayfly spinner is!? I have always thought that it was a mayflies last life stage before it dies. But i have heard it's a separate mayfly from the actual; such as a march brown dun vs. a spinner, the mating stage, blah blah blah and more. Whats up here guys i want to know?
Most of us fish our whole lives..not knowing its not the fish that we are after.

Hi Jess,

When mayflies hatch, the duns fly off the water to find a safe place to molt into fully mature adults or spinners. This usually takes a day or two. They then come back to mate and lay their eggs. They die soon after with many ending up in the water. The spinner looks just like the dun but usually shinier, perhaps a little darker, and with clearer wings. Caddis and stoneflies don't molt after hatching.

the usual mayfly life cycle goes like this:

egg (laid in water)
nymph (molts several times as it grows in the water)
dun (a winged stage that leaves the water, but does not mate; this stage molts to form the next state)
spinner (the sexually mature stage that mates and lays eggs)
