Male Cinygmula (Dark Red Quills) Mayfly Spinner Pictures

 This male was collected from the same cloud of spinners as this female and is probably the same species. I'm tentatively calling them both Cinygmula for now, but I'm really not sure about that ID yet.

This mayfly was collected from Rock Creek on August 17th, 2018 and added to Troutnut.com on June 13th, 2019.
