Baetis

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.

With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.
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.

This mayfly was observed in the Croton system yesterday. A size 14 maybe. My best guess is drunella cornuta based on photos from this site, but I'm stumped.

Hi Larry-

Welcome aboard. I believe this female subimago to be of genus Leptophlebia. If you lighten the image, the characteristic abdominal banding becomes more apparent.

Thanks for the quick response. Someone else thought it might be a hendrickson. I've fished this stream for years and never seen this exact coloration.

A little early for drunella? The legs don't look right for drunella, either, I think. And I think the black quill typically has a very short middle tail. Could it be a hennie? What size was it? Oh and pretty photo, by the way. More to consider https://www.inaturalist.org/guide_taxa/35362
