Male Maccaffertium ithaca (Light Cahill) Mayfly DunMale Maccaffertium ithaca (Light Cahill) Mayfly Dun View 6 PicturesBased on the identical size, shape, and relative proportions of different body parts, I'm pretty sure this dun is of the same species as two spinners I collected at about the same time. The color is dramatically different, but that's to be expected with many of these species in the transition from dun to spinner.
