This female spinner was deceased when photographed, so the posture is unnatural, but it was a substantial hatch and clearly worth imitating (with wet flies to imitate the sunken ovipositing females) so I went ahead with the photos.

It was collected in association with a male spinner.

This mayfly was collected from Silver Creek on September 4th, 2020 and added to Troutnut.com on September 18th, 2020.
