I thought as long as I was gonna start tying some scuds for Spinney I needed a good Callabaetis Nymph pattern for Spinney too...I figured asking here is easier than driving over to the Colorado Angler...
The baetis i usually tie for stillwater applications are weighted and non weighted...size 14 or 16, with dark muskrat and a pheasant tail...um, tail. when i weight them i slide a dark tungsten bead over the hook and tie it in where the body is, and then dub over it...the whole thing is wrapped in small gold wire, and i make sure to cement the head and tail to make it more durable. make sure you pick the body pretty good to make it appear as fuzzy as possible.
yeah, for the most part a gold ribbed hairs ear will work, along with pheasant tails...size 14 and smaller. for baetis dries a Adams usually works fine.
last year i had good success with the skip nymph tied with a silver bead,mint green with touch of olive dubbing on tail and flashback wingcase as suggested by someone on the net. it ended up being my best fly during the callabaetis hatch.
