All creatures great and small have a purpose on this earth no matter how annoying they are to humans. Even flies have their jobs in the bigger scheme of things, which would break down if just one of the elements in the loop was to die out. Frogs live off flies, other creatures live off frogs and so on and so on down the food chain. Although the mayfly has many predators, they also have a useful purpose, which is not just to breed and multiply. Using other things in nature like trees, flowers and fruits, the mayfly lives a very happy life until it is time to die off. The mayfly is classed as an insect because of its insect features, like the six legs and three segmented body. Like other flies, the mayfly has wings and the ability to fly, which makes it easy for them to collect foods and do what they need to do to survive.
Depending on the species of mayfly, the adult may only live long enough to transform from pupil stage, eat food, breed and then die. Sometimes, they do not even live long enough to eat for long. When a group of mayflies get together, predators like birds, spiders and other insects get together for a real feast. With millions of mayflies being born at one time, it is easy to eat most of them and still continue the cycle of life. The mayfly is actually one of the oldest living insects from many thousands of years ago, and are part of the same family as the dragonfly. During the nymph stage, which is their initial stage after the insect lays eggs in the water, the nymph is born and wriggles around eating and trying not to be eaten until it is ready to change into a mayfly.
There are thousands of different mayfly species all around the world, and they known by different names including the dune bug, Lake Fly, day fly, green bay flies and fish flies. The last name is obvious because the fish like to eat the larvae and the flies breed in water that contains fish. Some of the biggest bug collections in the world hold several hundred species of the mayfly from all different climates and terrain.
