This one seems to lead to Couplet 35 of the Key to Genera of Perlodidae Nymphs and the genus Isoperla, but I'm skeptical that's correct based on the general look. I need to get it under the microscope to review several choices in the key, and it'll probably end up a different Perlodidae.

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.

Male Leptophlebia cupida (Black Quill) Mayfly Dun Pictures

This Leptophlebia cupida dun was extremely cooperative, and it molted into a spinner for me in front of the camera. Here I have a few dun pictures and one spinner picture, and I've put the entire molting sequence in an article.

Saw a nice Leptophlebia cupida/nebulosa spinner today while I was sitting on the front porch; it met its demise in my wife's soda, unfortunately. That's the first one I've noticed this year. What else, if anything, is everyone seeing so far this spring? The Ameletus from the stream behind my house will be hatching soon, maybe yet this weekend, if the weather cooperates.
