Male Ephemerella aurivillii Mayfly SpinnerMale Ephemerella aurivillii  Mayfly Spinner View 15 PicturesThis spinner molted from a dun after being photographed, and the dun form is listed here as a separate specimen. I've rarely found a more cooperative and photogenic mayfly.

Female Baetidae (Blue-Winged Olives) Mayfly SpinnerFemale Baetidae (Blue-Winged Olives) Mayfly Spinner View 12 PicturesThis species is probably in Centroptilum, Cloeon, or Procloeon. I captured this spinner on the same night as a dun which is probably of the same species.

Male Ephemerella aurivillii Mayfly DunMale Ephemerella aurivillii  Mayfly Dun View 14 PicturesThis is the most widespread species of Ephemerella, and also the most abundant in some places, but nobody I've talked to seemed to know what its duns looked like, and there were no pictures of its duns online or in any angling books. That mystery is solved with this male dun, which hatched from a definitively identified nymph.

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?
