Re: lake erie mayfly hatch!!!
The bigger ones are hex and i think the smaller mayflies are brown drakes, They usually hatch separately but they came off at the same time this year. They both generally hatch at night the times they are available to the fish are the nymph, the hatch and a few days later at the spinner fall when the females lay their eggs and die on the water---usually again at night.
The perch were eating the midges (muckleheads or as you call them "sand flies")
All you have to do is get your # 18 nymph down to 30-40 ft.
