The name implies this fly was conceived to represent a scud or a beetle. Pete Ouellette calls it a “great little versatile wet fly” that he likes to use in the summer in high mountain streams. The Sceedle can produce on the surface, but it is even better when fished as a shallow wet fly.
This pattern calls to mind a summer evening on a bluegill pond. A school of bluegill were feeding in the shallows, and I used a sparsely tied beetle pattern to catch close to 30 fish before we all tired of the game.
Tie this pattern on a No. 12-14 wet fly hook. For the shell back, use turkey quill. Build the body with peacock herl and finish with an undersized olive grizzly hackle wrapped palmer-style.
