Pale Morning Dun Patterns

As a companion Four-pack Set to my Sulphur Dun Ephemerella invaria patterns on http://www.myflies.com/ I am also offering the same series of mayfly dun pattern styles for the Pale Morning Dun, which is also in the same Ephemerella genus as the sulphurs, the PMD species being named excrucians.

Since I have personally only ever encountered one PMD hatch, I took some information from the site Troutnut.com – http://www.troutnut.com/hatch/459/Mayfly-Ephemerella-excrucians-Pale-Morning-Dun and I would like to express my thanks for the helpful information presented there. Troutnut has a lot of good, no nonsense aquatic insect information. I recommend visiting that site.

Since the Pale Morning Dun is one of the most widely-ranging and long-lasting hatches of its geographical distribution, I considered the marketing aspect of my fly tying livelihood and decided to offer the PMD in a series of pattern styles as I did for the widely distributed sulphur mayflies of the east and mid-west.

The “PMD’s” are a very eagerly anticipated hatch on many streams, particularly in the mid-west and western US. These mayflies occur with variations in color and size depending on the location, from a #14 to a #18. This offering of four different dry fly pattern types and hook sizes is intended to increase the anglers chances of success when fishing a PMD hatch. Trout can be selective to pattern types, particularly on flat water, so it is beneficial to the angler to be prepared with more than one style and size of dun pattern when fishing this hatch. This proven collection of Pale Morning Dun patterns helps solve the difficulties of fishing PMD drys to finicky trout. All four dun patterns are tied with split tails.

Pale Morning Dun dun patterns, left to right: Parachute Dun, Thorax Dun, Comparadun, Quill-body Comparadun, hook sizes here are #14. All flies tied and photographed by Don Bastian.

The PMD Comparadun is a no-hackle pattern that rides low, yet stays  on the surface film. The light natural color deer hair wing is highly imitative and easy to see, and the split tails stabilize the pattern and offer added mayfly realism. Comparaduns land right-side up on nearly every cast. They are an excellent pattern choice for smooth water and moderate riffle currents. This pattern has a slim, dubbed abdomen with a thread ribbing and a more robust thorax, providing a natural imitative mayfly silhouette for increased realism. This design factor helps trigger confident takes from trout.

PMD Comparadun

Hook: Standard dry fly hook, #14 – #18

Thread: Danville Flymaster Light Olive #61

Wing: Natural light deer hair

Tails: Light dun Microfibetts six fibers split 3/3

Abdomen: Light olive rabbit dubbing, abdomen reverse-ribbed with tying thread

Thorax: Light olive rabbit dubbing, built up larger than the abdomen to present a natural mayfly silhouette

Head: Light olive

PMD Comparadun

Pale Morning Dun Comparadun

The PMD Quill-body Comparadun is a personal pattern design variation that has a more realistic body silhouette with a slim, waxy-smooth abdomen that contrasts with the more robust fur-dubbed thorax. The abdomen is made from a synthetic quill material that is highly translucent, and it also floats, thereby adding increased flotation to this pattern. This shade of light olive on the abdomen very closely imitates the natural color of the PMD’s.

PMD Quill-body Comparadun

Hook: Standard dry fly hook, #14 – #18

Thread: Danville Flymaster Light Olive #61

Wing: Natural light deer hair

Tails: Light dun Microfibetts six fibers split 3/3

Abdomen: White Sexi-Floss (aka Flexi-Floss, Dyna Floss, Super Floss, etc.) Winding the white Sexi-Floss over the light olive thread creates a very translucent abdomen. The Sexi-floss is tied in at the thorax. (See my other posts on this topic, use the search tab). The translucent nature of this material allows the thread color to predominate. This stuff is the best synthetic quill substitute available. And, it floats! This increases the pattern’s buoyancy.

Thorax: Light olive rabbit dubbing, built up larger than the abdomen to present a natural mayfly silhouette

Head: Light olive

PMD Quill-body Comparadun

PMD Quill-body Comparadun.

The PMD Parachute Dun is made with the same abdomen of synthetic quill material as the Quill-body Comparadun, and has a dubbed thorax, but it has a poly-post wing and a parachute hackle. The advantage of parachute duns provides a highly-visible, low-floating, imitative design. It is generally considered a better dry fly pattern for fishing riffles, runs, and typically rougher pocket water than the no-hackle Comparadun.

PMD Parachute Dun

Hook: Standard dry fly hook, #14 – #18

Thread: Danville Flymaster Light Olive #61

Wing: Light dun polypropylene

Tails: Light dun Microfibetts six fibers split 3/3

Abdomen: White Sexi-Floss (aka Flexi-Floss, Dyna Floss, Super Floss, etc.)

Hackle: Light dun or ginger – I anchor the butt of the hackle stem to the base of the wing post

Thorax: Light olive rabbit dubbing, built up larger than the abdomen to present a natural mayfly silhouette

Head: Light olive

PMD ParachuteDun

PMD ParachuteDun

The PMD Thorax Dun offers yet another pattern variation that helps fool trout. The wing is placed a little farther from the hook eye than the Parachute Dun, and the hackle is wound conventionally, but clipped on the bottom. Like all the patterns in this set, the Pale Morning Dun Thorax Dun features a split tail with the synthetic, translucent quill abdomen and a fur-dubbed thorax. Like each pattern in this collection, the Thorax Dun offers a different silhouette on the surface. Being prepared with multiple fly pattern designs for any mayfly hatch is an asset to the angler.

PMD Thorax Dun

Hook: Standard dry fly hook, #14 – #18

Thread: Danville Flymaster Light Olive #61

Wing: Light dun polypropylene

Tails: Light dun Microfibetts six fibers split 3/3

Abdomen: White Sexi-Floss (aka Flexi-Floss, Dyna Floss, Super Floss, etc.)

Hackle: Light dun or ginger, clipped flat on bottom

Thorax: Light olive rabbit dubbing, built up larger than the abdomen to present a natural mayfly silhouette

Head: Light olive

Set of Four – These four PMD patterns are also being offered together in an attractive boxed set. The set is identified with a printed label, a signature card, the flies are mounted on foam strips, and they are beautifully packaged in a clear plastic case. This attention to detail and quality of the boxed set makes this a tasteful gift.

What it imitates: Ephemerella excrucians mayfly sub-imago, Pale Morning Dun (PMD)

When to fish it: The PMD is an ubiquitous mayfly, very abundant throughout the west, and there is a wide range of dates for their emergence. It is often best to consult local sources for hatching information. Despite their name, they often hatch in the afternoon and evening depending on conditions and locale.

Where to fish it:  Pale Morning Duns inhabit most water types, tailwaters, spring creeks, freestone streams, rivers, and some ponds and lakes, except warm water and infertile high country lakes.

How to fish it:  PMD patterns can be fished on 5x to 7x tippet, depending on water type. This hatch is prolonged, and on heavily-fished waters, trout can become drift-shy, requiring very precise presentation to fool them into taking your fly. Accurate casting and drag-free drifts are essential for success. On smooth water long leaders of 12 – 14 feet are necessary. Two or more pattern variations of the PMD can increase your chances for a good day on the water.
