Eatonia was a newsletter established to facilitate communication among scientists working on a group of aquatic insects in the order Ephemeroptera, more commonly known as mayflies. The newsletter is named after Rev. Alfred E. Eaton who studied mayflies in England in the late 1800’s and is considered the “father” of the modern classification of mayflies.
