This hopper pattern was created in the 1950's by Ed Shenk, from right here in good ol' Pennsylvania. It's simple, fairly easy to tie, and can do wonders on a trout stream in mid-summer.
But a word of warning, if your not careful, this can start to look like a muddler minnow.
#8 hook (can be tied on 14-6)
Body: Hare's Ear Dubbing
Wing: Inner - Mottled Turkey Quill, Outer - Grey Deer Belly
