The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
This 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.
This mayfly was collected from the Delaware River in New York on May 13th, 2007 and added to Troutnut.com by Troutnut on May 18th, 2007.
