A Flashy and Unweighted Mayfly Nymph

A gaggle of Flashabaetis nymphs |
The nice thing about unweighted patterns is that they can actually be a little more multi-purpose than bead-head flies. It's tough to get a bead head to sink slower, but especially in lakes or slower moving water, you just need to add a little more time and the unweighted fly can reach your target zone and even hang there longer. My little cutthroat excursion above was a pretty obvious example of this where the unweighted fly (same style) outscored their beaded buddies by a huge margin. I could only chalk that up to having the fly maintain a more natural descent or movement in the water and possibly remaining in the fish's view for more time.
The Flashabaetis was born out of this concept with some added flashiness to help get a little more attention in the water. It's a really fun pattern to tie and you can mix up the color schemes to imitate a lot of different mayflies, although I'm usually tying them for Pale Morning Duns (PMD's), Baetis (Blue winged olives) or Callibaetis nymphs.
