When you need a fly for the stonefly hatch that is big and floats like a cork, the Terranasty is for you. Tied with a foam body, spiraled with dry fly hackles, and a Poly under wing with an Elk over wing this fly is virtually unsinkable. The rubberlegs twitch and move in an irresistible way, making this an excellent choice for most large stonefly hatches.

Great OP Cutthroat fly in the Summer/Fall

Size 8 in Orange makes a great October Caddis as well.
