The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
posts stick straight up unlike the natural's wings
I tie a version on a scud hook with a natural goose/turkey biot body, gray post and dark dun parachute hackle...Can't see it, but when the early season Baetis and Little Mahoganies are about they love it...
He ties in the post with a slant back like the natural mayfly wing. Ties it in like you might an elk-hair caddis. He leaves the butt-ends on and ties on a hackle and winds it beneth the wing and the butt ends...Ties it off and trims the front butt-ends off low...
