This male Stenacron interpunctatum spinner rests on a wooden dock over the warmwater lake on which he was found.  Many of his kind were in the air over parts of the lake at dusk.

I know I'm a little out of season, butI was curious if you had any shots of Stenacron Interpunctatum next to your hook quide, or could just give me a size range. I was thinking they were 14-16 but could be wrong. Also you have written that Stenacron Interpunctatum were rarely called cahills. If so what mayfly is it that i'm after (that is common name "cahill"). The stenacron look the same to me, but i have also never kept and memorized any specimens.
Thanks
Jeff
