Old Flies in New Dresses: How to Dress Dry Flies with the Wings in the Natural Position and Some New Wet Flies

In Short

Published in 1898, this handbook is a focused, methodical entry in Victorian angling literature. Charles Edward Walker addresses a common flaw in fly-tying: artificial dry flies are routinely tied with upright, flared wings, whereas natural insects fold their wings flat or angled along their bodies when at rest. Walker provides precise tying instructions for species like the Alder-fly and Cow-dung fly, defended through aquatic biology, fish anatomy, and personal stream observations. It survives as a classic example of nineteenth-century natural history applied directly to practical craft.

The Story

The book opens with a clear proposition: traditional fly-makers rely on outdated patterns that misrepresent insect morphology. Walker observes that when natural flies fall onto the water, they briefly struggle and then rest with their wings folded in species-specific positions. Artificial flies tied with stiff, upright wings present an unnatural silhouette to trout. To fix this, Walker outlines exact geometrical wing placements for four major insect families—Sialidae, Trichoptera, Diptera, and Perlidae—arguing that mimicking the insect at rest yields far more effective strikes.

Before detailing his dressings, Walker defends the necessity of matching real insect colors. He addresses Sir Herbert Maxwell’s controversial theory that fish are color-blind and respond only to light and shadow. Drawing on micro-dissections of trout eyes, Walker demonstrates that a trout’s retina contains a dense layer of cones similar to the human fovea centralis. Because trout possess the anatomical apparatus for acute color vision, he insists that anglers must match natural hues rather than rely on monochrome shades.

From vision theory, Walker moves to practical instruction. He provides step-by-step methods for stripping quill feathers, shaping rounded wing tips, and securing silk and hackle so the materials maintain their natural posture on the hook. He then categorizes key insect species, supplying exact recipes for the Alder-fly, Sand-fly, Red Sedge, Willow-fly, Yellow Sally, Cow-dung fly, and various small Diptera known as "curses."

In the book’s second movement, Walker shifts focus from floating surface flies to sub-surface wet flies. He contends that many popular wet flies do not resemble drowned land insects at all; instead, fish strike them because they mimic free-swimming aquatic creatures like water beetles, bugs, and crustaceans. To prove his point, Walker details his development of an artificial Corixa (water boatman), complete with stiff starling-quill legs tied at right angles to simulate a rowing motion when jerked through the water. He extends this logic to caterpillars and freshwater shrimps (Gammarus pulex), citing aquarium trials where trout aggressively seized live shrimps. He concludes with practical streamcraft, offering advice on line maintenance, casting technique, and greasing flies to maintain buoyancy without distorting natural coloration.

How It Unfolds

The problem defined Walker identifies widespread inaccuracies in commercial fly-tying, noting that makers routinely fix wings in outward, upright angles that contradict natural insect anatomy at rest.

The anatomy of fish vision Dissecting the trout's retina, Walker argues that the presence of tightly packed cones indicates sharp, color-sensitive vision, making accurate color matching essential for effective lures.

Methods of construction Walker lays out precise workshop techniques for preparing quill feathers, rounding wing edges between the fingers, and tying hackle to ensure wings rest horizontally or folded across the body.

Cataloging the dry patterns The author provides exact material recipes and tying instructions for key surface species, detailing the specific wing postures of Sialidae, Trichoptera, Diptera, and Perlidae.

The sub-surface shift Transitioning to wet flies, Walker theorizes that fish take underwater lures not as drowned flies, but as active aquatic creatures such as water bugs and crustaceans moving through the water.

Engineering the Corixa Walker describes creating a water boatman imitation using starling-feather legs tied at right angles, which flex and spring back under water to replicate natural swimming mechanics.

Observations on aquatic food Drawing on riverbank dissections and aquarium feeding trials with freshwater shrimps, Walker demonstrates how rapidly trout fatten on crustaceans and underwater invertebrates.

Streamcraft and application The guide closes with practical advice on line floating using vaseline and beeswax, delicate casting above the surface, and proper fly maintenance along the riverbank.

The People

Walker’s text is a work of instructional non-fiction, so its "characters" are the naturalists, angling theorists, and key organisms that drive his arguments.

• Charles Edward Walker: The author and master tier. Driven by a desire for observational accuracy, he seeks to bridge entomology and practical angling. He spends hours dissecting fish eyes, examining gut contents, and experimenting with feather mechanics at the vise.
• Sir Herbert Maxwell: The prominent angling theorist whose monochromatic vision hypothesis serves as Walker's primary intellectual foil. Maxwell claims fly color is irrelevant to fish, prompting Walker's detailed anatomical rebuttal.
• The Trout: The ultimate judge of the fly-tier's craft. Depicted as a highly sensitive predator with acute color vision and a sharp eye for natural wing silhouettes and movement.
• The Corixa and Gammarus pulex: The aquatic water bug and freshwater shrimp. These organisms represent Walker's case for sub-surface imitation, shifting the tier's focus from land-based insects to aquatic prey.

In Its Own Voice

"What I have tried to do, is to work out and bring down to a definite rule the position in which the wings of the imitations of the various kinds of flies should be placed."

"As we find in the retina of the trout, no material difference from the fovea centralis of the human retina, we have no reason to suppose that the visual powers of the whole of the retina of the trout, should differ in any way from the visual powers possessed by the fovea centralis..."

"When the shade and colour and size of the fly is the same as one of these aquatic creatures, I am sure that the fish takes it, not for a fly, but for one of them."

What It's Really About

Old Flies in New Dresses is fundamentally about the relationship between close observation and practical craft. Walker argues that fly-fishing should not rely on unexamined tradition or aesthetic conventions, but on empirical evidence gathered from nature. Underneath the specific recipes for wool, silk, and feathers lies a broader philosophical inquiry into non-human perception: how a fish views light, color, and motion through the boundary of the water's surface. Walker insists that by understanding the physical mechanics of an insect at rest and the microscopic anatomy of a trout's eye, the angler can discard ineffective traditions in favor of functional design.

Why Read It Today

This book appeals directly to fly-fishers, tiers, and readers who appreciate Victorian natural history and hands-on craft. Walker writes with the clear, methodical style of a late-nineteenth-century researcher, blending streamside experience with laboratory observation. The text retains a charming, practical tone—found in moments like Walker chasing caterpillars on riverbanks or testing line wax recipes.

Readers should expect archaic insect names, nineteenth-century tackle terminology, and precise descriptions of fly-tying steps using vintage materials like seal's fur, starling quills, and heron herl. While modern hook numbering and synthetic materials have evolved since 1898, Walker's core observations regarding insect posture and fish vision remain entirely relevant. It offers an engaging, unpretentious window into how science and observation transformed traditional field sports at the turn of the twentieth century.
