Elk Hair Caddis

The Elk Hair Caddis, created by Montana guide and fly tier Al Troth, is perhaps the most iconic and versatile caddis dry fly pattern ever designed. Its combination of elk hair wing, wire-ribbed palmered hackle, and slim dubbed body creates a highly visible, durable pattern that floats exceptionally well even in fast, rough water. The elk hair wing provides both flotation and a natural, buggy silhouette that closely matches adult caddisflies. This pattern excels as both a searching fly when no specific hatch is active and as a precise match during caddis hatches. Available in multiple color variations (tan, olive, brown, orange, yellow), it can effectively match a wide range of caddis species from small spring caddis to large fall October caddis.

Step-by-Step Instructions

  1. 1

    Thread Base and Rib

    Start the thread about two eye lengths back from the eye and make a thread base back to the bend. Return the thread to the starting point, tie in a piece of extra-fine copper wire and wrap back over it to the bend.

  2. 2

    Body

    Dub a tapered body from the bend to the starting point.

  3. 3

    Hackle Tie-In

    Tie in a brown rooster neck hackle by its butt at the front edge of the dubbed body.

  4. 4

    Palmer the Hackle

    Spiral wrap the feather back over the body with six or seven turns to the bend.

  5. 5

    Counter-Wrap the Rib

    Catch the hackle tip with the wire and wrap the wire forward through the hackle to the starting point. Trim the excess wire and the hackle tip.

  6. 6

    Wing

    Cut, clean and stack a clump of elk hair. Measure it so the tips reach the hook bend, lay it on top of the hook just behind the eye and make two tight turns of thread, cinching them down by pulling toward you.

  7. 7

    Thread Band and Head

    Build a small band of tight thread wraps to anchor the wing and whip finish on the band. Snip the wing butts off square in front of the band so they form the head.

How to Fish the Elk Hair Caddis

The Elk Hair Caddis excels when fished actively. During caddis hatches, use a dead drift but be ready to twitch or skitter the fly to imitate the skittering behavior of natural caddis adults on the water surface. The pattern floats exceptionally well, making it ideal for fast water, riffles, and pocket water where other dry flies might get swamped. Can be fished as a searching pattern when no specific hatch is active, or as a precise match during tan, olive, green, or brown caddis hatches. For selective trout, try a subtle twitch at the end of the drift. The elk hair wing creates a visible silhouette that fish can spot even in broken water. Color variations allow matching local species - tan/olive for most western caddis, orange for October caddis, brown for black caddis.
