The Brown Roach is an old pattern from the Missouri Ozarks originally tied on a jighead. Here it’s on a jig hook with a tungsten bead, with a couple other slight tweaks. Sometimes derided as a “pellet fly,” this pattern works just fine on wild or holdover trout that either have never seen a pellet or have long since stopped eating them. I think it suggests a cased caddis or possibly a sowbug. The basic pattern is also good in other colors for various species. Try it in black, white, chartreuse, and yellow for stocked trout and panfish, or in other earth tones for wild and holdover trout.
