Male Paraleptophlebia (Blue Quills and Mahogany Duns) Mayfly SpinnerMale Paraleptophlebia (Blue Quills and Mahogany Duns) Mayfly Spinner View 15 PicturesI wasn't actually fishing the river where I caught this one. I was just scouting, didn't like the look of the water, and as I was walking back to the car this little dun landed on my vest. Why can't they all be so easy to collect?

Female Ephemera varia (Yellow Drake) Mayfly DunFemale Ephemera varia (Yellow Drake) Mayfly Dun View 7 PicturesThis yellow drake dun hatched out of my aquarium over a month before her brethren in the wild are slated to emerge. She seems a bit small, and that might be the reason.

Isonychia bicolor (Mahogany Dun) Mayfly NymphIsonychia bicolor (Mahogany Dun) Mayfly Nymph View 7 PicturesThis Isonychia bicolor nymph from the Catskills displays the prominent white stripe sometimes characteristic of its species. This is the first such specimen I've photographed, because members of the same species in the Upper Midwest have a more subdued stripe (and were once thought to be a different species, Isonychia sadleri). The striking coloration on this eastern nymph is more appealing.
