The Fly-fisher's Entomology
The Fly-Fisher's Entomology, Illustrated by Coloured Representations of the Natural and Artificial Insect and Accompanied by a Few Observations and Instructions Relative to Trout-and-Grayling Fishing, first published in 1836 by Alfred Ronalds (1802–1860), was the first comprehensive work related to the entomology associated with fly fishing. Although the work was Ronalds' only book, it was published in 11 editions between 1836 and 1913 and has been extensively reprinted in the last 100 years. Synopsis

The Fly-fisher's Entomology is the archetype fly-fishing how-to book. Most fly-fishing historians credit Ronalds with setting a literature standard in 1836 that is still followed today. Describing methods, techniques and, most importantly, artificial flies, in a meaningful way for the angler and illustrating them in colour is a method of presentation that can be seen in most fly-fishing literature today. As the name implies, this book is mostly about the aquatic insects—mayflies, caddisflies and stoneflies—that trout and grayling feed on and their counterpart artificial imitations. Less than half the book (chapters I–III) is devoted to observations of trout, their behaviour, and the methods and techniques used to catch them. Most of this information, although enhanced by Ronalds' experiences and observations, was merely an enhancement of Charles Bowlker's Art of Angling (first published in 1774 but still in print in 1836). Ronalds introduced several new ideas, however, in Chapter I. His experiments and observations led him to describe and illustrate the trout's Window of vision, a concept an understanding of which is still essential today. Vincent Marinaro, in his classic work In the Ring of the Rise (1976), credits Ronalds with discovering and documenting this window and includes a reproduction of plate II – Optical diagrams in his book. Ronalds’ physicist brother Sir Francis Ronalds quantified the phenomenon for Alfred using his knowledge of optics. In the sub-chapter "Haunts", through discussion and illustration (plate I), Alfred Ronalds introduces the idea known today as reading the water to help the angler identify the most likely locations in the stream to find trout. The real meat of Ronalds' book was Chapter IV: Of a Selection of Insects, and Their Imitations, Used in Fly Fishing. Here, for the first time, the author discussed specific artificial fly imitations by name, associated with the corresponding natural insect. Organized by their month of appearance, Ronalds was the first author to begin the standardization of angler names for artificial flies. Prior to The Fly-fisher's Entomology, anglers had been given suggestions for artificial flies to be used on a particular river or at a particular time of the year, but those suggestions were never matched to specific natural insects the angler might encounter on the water. The following is a typical discussion:

Author
Alfred Ronalds was born in Highbury, London in 1802, the 11th of 12 children. His father was a successful merchant and his eldest brother, Sir Francis Ronalds, became famous for pioneering the electric telegraph. In 1817 at the age of 15, Ronalds took an apprenticeship as an engraver, lithographer and copper-plate printer. In 1830 he moved to Tixall, Staffordshire. He married his first wife, Margaret Bond, a local girl, in 1831. In Staffordshire, Ronalds took up the sport of fly fishing, learning the craft on the rivers Trent, Blythe and Dove. On the River Blythe, near what is today Creswell Green, Ronalds constructed a bankside fishing hut designed primarily as an observatory of trout behaviour in the river. From this hut, and elsewhere on his home rivers, Ronalds conducted experiments and formulated the ideas that eventually were published in The Fly-fisher's Entomology. He combined his knowledge of fly fishing with his skill as an engraver and printer, to lavish his work with 20 colour plates. In 1844, Ronalds moved his family to Dolgelly North Wales and in 1846 he moved to Brecon in South Wales, then to Cwmback, Llanalwedd, to become a full-time tackle maker and fly tier. In 1847, his first wife Margaret died during childbirth. In 1848 with six of his children, Ronalds moved to Melbourne, Australia and set up an engraving business. The gold rushes of the 1850 eventually found Ronalds settled in Ballarat, where he died suddenly of a stroke in 1860. He never returned to England. Contents
