That's the name of this streamer. Designed and tied to represent a juvenile brown trout. Brown trout are notorious meat eaters, and not at all ashamed to dine on their own, this is why a streamer can be so effective on them under certain instances.
Wild browns can be taken in small streams on dry flies, and they will take them quite readily when the fly is presented well. They like the comfort of a position in the stream where ambush is at their means. Fish the shadows, along a fallen log, root jams, near undercut banks. Fishing low light times are also a plus.
While the beauty of a brook trout in my opinion is tops, the brown is a close second. Their spotted bodies are very handsome. They are strong in their abilities to shake a fly or take you into a root tangle and say goodbye.
The wild brown taken in a small stream, with a 3wt is a tussle that's hard to beat.
