Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

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.

This mayfly was collected from the Teal River in Wisconsin on May 27th, 2005 and added to Troutnut.com by Troutnut on May 16th, 2006.

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.
