27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Female Leptophlebia cupida (Black Quill) Mayfly Spinner Pictures

This large female Leptophlebia spinner emerged from a nymph I was holding in my room one night. I didn't have time to photograph her and she molted into a spinner before I was home from work in the evening. So here she is as a spinner. I wish I had more photos at more angles, but she flew off and I couldn't find her.

This mayfly was collected from unknown in Wisconsin on May 18th, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.
