Re: lake erie mayfly hatch
George, I would say they are all Hexagenia; assuming they were all the same size. The darker colored one is probably a freshly hatched dun, the lighter colored ones would be approaching the mating and egg laying stage. One of the imitations I use is a Robert's Yellow Drake. Yellow died deer body hair, white deer hair from the belly, and a barred saddle hackle wound parachute style around the wing...About everything that swims will eat them. If there's a hex hatch on the Vermillion you can have a ball with the Smallies!
