Caddis Larvae Hook: TMC 2457 Size: 14 ~ 18 Thread: 6/0 Olive (Flat Thread e.g. UTC 70 or Gudebrod) Abdomen: UV Light Olive Ice Dub Over Wrapped With Fluorescent Chartreuse UTC Vinyl Rib, Size Small Thorax/Legs: Dark Brown Awesome Possum And Mottled Brown Medallion Sheeting Head: Brown Glass Seed Bead Note: For me, this fly is best fished as a trailing fly behind a heavily weighted nymph in late March and early April. Like the Halo Emerger, fish it through the riffles or in swiftly moving, deeper water.
