From FlyToTie:
“There is no other time like the hatch of big mayflies. The trout go wild and aren’t as careful as they normally are. The flies are big and float well, you can use a thicker tippet and not worry about it breaking as much. We found that detached body mayflies like this one work wonders on trout. This time we’re tying a two-toned version. It may not make a big difference but it sure looks great and will catch fish at least as well as any other detached body mayfly.”
