- - - - Mayflies are the fastest water to air transforming insect in the world. They swim up to the surface, and just jump out of their larval skin. Within a second or so, they are flying. This is because they are a very ancient group of insects, that many fish have made a living by eating them. The fish don't see them until they appear with their wings on the surface. They've been pressured to become faster and faster at escaping. They spend their larval stage under rocks in cold running water. You can find them clinging to rocks underwater.

Fishermen use lures that resemble mayflies, or sometimes they use a real mayfly.
