This is one of my favorite patterns to try if I don’t know what to try. It seems to imitate small stoneflies and mayflies and will even pick up caddis when they are hatching. Also it is easy to make so I don’t feel as bad when I break one off on the bottom or get stuck high in a tree (happens way too often..).
Hook: size 12-18 straight nymph or scud hook
Bead (if used): 2.8mm black or gold head
Thread: 70 Denier to match the body
Tail: Brown goose biot
Body: Bronze wire
Thorax: Peacock hearl
Wing: Arizona Dubbing brown or olive
I will be tying an unweighted version below, if you want a little faster sink just add a bead head.
Experiment with what color combo works best on your local lakes and streams, the combo above seems to do well up in northern Arizona and southern Colorado but I’m sure theres a better combo out there I have yet to find!
