Ephemera varia

In the early aquatic stages, the mayflies are called Naids that feed under water. During the last aquatic stage Naids leave the water, molt and become airborne. Another transformation brings forth the adult mayflies. Adults have no mouth parts for feeding. Swarms of males fly up and down, seize a female in flight, and mate with her. In a short time eggs are laid on nearby aquatic plants. Certain species of mayfly might live for only a day; others may live for 4 years as aquatic naids.

Local fishermen say it's time to get out the tackle box when Mayflies swarm.

This is a very fragile insect; long tails; triangular wings that are transparent and held above the body at rest. The hind wings are very small. Its preferred habitat is forests, fields and yards.
