This particular tying has been done in the Universal Baetis pattern originated by Hans van Klinken & Leon Links (1997). but can be tied in any format and size you wish to represent other invertebrates.

  • Hook – Ahrex FW503 Dry Fly Light, size 16
  • Tail and Wing – Deer hair similar to X Caddis deer hair in the colour to suit the hatch
