Simple Foam Caddis Tying Tutorial

May 17, 2015

Simple Foam Caddis from Hopper Fishing

PATTERN DESCRIPTION: The Simple Foam Caddis is the best floating, easy to see caddis pattern that is simple to tie and simply catches fish. I’ve had tremendous luck during the Mother’s Day Caddis hatch here on the Yellowstone River near Livingston, Montana with this pattern fished as either a single dry or used as a dry-dropper combo trailing a small caddis nymph or soft hackle. This foam pattern can be tied in many different colors of foam and thread to match October Caddis, Spruce Moths and black caddis. I have added Sili Legs and hackle on bigger patterns like size 8-12 for buggy looking attractor patterns. One of my favorite variations includes an orange poly wing and 1mm tan foam. Best thing about this pattern is that it floats forever. No dry shake or flyagra required. Tie a few up and let me know what you think.

MATERIALS NEEDED:

Hook:Dai Riki 060 or standard 1xl dry fly hook

Thread/Body: Iridescent Veevus Thread – Olive

Underwing: 1mm tan, cinnamon or brown foam

Wing: Poly Wing – 1/2 strand

Hackle: Grizzly Hackle

Tying Simple Foam Caddis

Step 1: Wrap a thread base/body with Iridescent Thread.  End thread about 1/4 hook length behind eye as shown above.

1mm foam strip

Step 2: Cut a strip of 1mm foam. Width of foam should be gap of hook in width, or little less.

Shape 1mm Foam Strip

Step 3: Cut a “V” shaped notch in foam strip.

Super Glue on Foam Caddis Pattern

Step 4: Apply a thin layer of superglue to the thread wraps from the barb, to the hanging thread only.

Tying in poly wing on simple 1mm foam caddis fly

Step 14: Apply 1/2 strand of poly yarn with 1 wrap of thread. You can try to substitute poly wing with z-lon or antron, but poly wing floats this fly like a cork while nylon doesn’t.
