The mayfly is medium-sized insect that is found in a variety of habitats all around the world. The mayfly is one of the most short-lived animals in the world and is most closely related to dragonflies and damselflies.
There are 2,500 known species of mayfly generally found close to water, all around the world with over 600 species of mayfly natively found in North America. Mayflies are extremely sensitive to pollution and can therefore only be found close to water that is of a high quality.
