Female Heptageniidae (March Browns, Cahills, Quill Gordons) Mayfly Dun Pictures

This female dun was kind of interesting, having a bit stouter proportions that I'm used to seeing. I forgot to photograph her against the measurement scale.

This mayfly was collected from the West Fork of the Chippewa River in Wisconsin on June 21st, 2021 and added to Troutnut.com by Troutnut on June 24th, 2021.
