Larval mayflies, which are referred to as naiads or nymphs, are aquatic (unlike adult versions) and some resemble adults, but lack the essential wings.

According to the Maine Department of Environmental Protection, adult mayflies live anywhere from 90 minutes to a couple of days, with the primary activity being mating to produce more larvae.

These insects feed on decaying plants or live algae and can be found in a wide variety of habitats.

These creatures are also very sensitive to pollution and are only found in high-quality, minimally polluted environments.

"Because they are found in a wide variety of habitats and are so widely sensitive to pollution, they are a valuable indicator of water pollution," the Maine Department of Environmental Protection said.

This is a strong indicator that the air and water quality are very good in the community and the surrounding environment.
