Penelomax septentrionalis Mayfly NymphPenelomax septentrionalis Mayfly Nymph View 12 PicturesThis is surely the most distinctive-looking species in Ephemerellidae. I like the rugged, spindly look. If mayflies made movies, Penelomax septentrionalis would probably play the supervillain.

Maybe I should take a break and get something to eat.
