(also known as shadflies)
Size: The mayfly grows up to 10 to 15 mm.
Habitat: Mayflies need a clean environment to reproduce and can lay eggs in both still and moving water. The babies (nymphs) live in the sandy mud at the bottom of the river where their food is found and the adults fly free wherever they like.
Diet: Nymphs eat algae, diatoms, and other organic matter.
Native/ non-native: Native to North America.
Status: Mayflies are currently stable but this could change if pollution in our bodies of water get worse.
Fun Fact: The mayfly is an insect that lives in the water as nymphs and as it grows comes out of the water to fly around and find more mates. Adult mayflies only live for a few hours or two days at the most.
