💡

Did You Know?

It is one of the earliest mayflies to emerge each spring, sometimes hatching when snow still lines the streambanks.

Arctic Mayfly

A small, delicate mayfly with transparent wings and two long tail filaments. Nymphs are agile swimmers in cold Arctic streams. Adults emerge for a very brief mating flight during the short Arctic summer.
