An Introduction to Entomology: Vol. 1 or Elements of the Natural History of the Insects — Edition Insights

Defending a Ridiculed Science

The preface makes plain that the authors wrote partly to rehabilitate entomology’s reputation. They note that “the idea of the trifling nature of his pursuit is so strongly associated with that of the diminutive size of its objects, that an entomologist is synonymous with every thing futile and childish.” This is not a generic complaint: it is a specific social diagnosis, tied to the fact that other sciences had already won fashionable acceptance. The authors argue that the very smallness of insects makes their study a test of intellectual seriousness. They do not, in the excerpts, claim to have changed public opinion; they simply state the obstacle. The tone is measured, even wry, but the underlying purpose is clear: to persuade the reader that insects deserve the same attention as plants or minerals.

Insects as Food for Birds: A Delicate Balance

One of the most detailed passages in the excerpts concerns the role of insects in bird diets. The authors list species—kestril, shrike, rook, ani, oriole, purple grackle—and describe how each depends on insects. They recount a striking anecdote: when New England farmers offered a bounty for purple grackles, the birds were nearly extirpated, and “insects increased to such a degree as to cause a total loss of the herbage.” The farmers had to import hay from Pennsylvania and even Great Britain. This example is used to argue that insects’ “powers of multiplication” were given precisely to feed birds. The authors do not moralize, but the economic logic is plain: destroying insect-eating birds backfires. The passage is built on specific testimonies—a friend’s dissection of a kestril, Kalm’s report on the little crow—showing the authors’ reliance on correspondence and travel literature.

Practical Entomology: Angling and Silk Gut

The excerpts also reveal a strong practical bent. The authors advise anglers to learn entomology well enough to distinguish species of Phryganea and other Trichoptera, and to know their emergence times. They then explain that the “Indian grass or gut” used for fishing lines is actually the dried silk vessel of the silkworm—or, according to Latreille, the silk reservoir itself. This kind of technical detail, drawn from both personal knowledge and foreign sources, is typical of the volume’s method. The authors are not content to describe insects in isolation; they constantly connect them to human crafts and industries. The passage on fishing gut is brief but precise, and it illustrates how the book aims to be useful to practitioners—farmers, anglers, and naturalists alike—not merely to armchair scholars.

Readers approaching this first volume should expect a work that is part apology, part natural history, and part practical manual. The authors’ voice is learned but not dry, and they frequently break into anecdote or economic calculation. The catalog subjects—insect societies, beneficial insects, host plants—are all present in the excerpts, but the book’s actual texture is more argumentative and applied than those labels suggest. Pay attention to the footnotes and the named correspondents: they reveal a network of observers across continents. The volume is best read as a period piece that shows how natural history was made respectable by linking it to agriculture, commerce, and sport.

That old Kirby and Spence book made me feel like bugs were little neighbors, not curiosities. It lingered because it showed how quietly they weave into everything—even our fishing lines. I stumbled on Illustrations of Exotic Entomology, Volume 2 — Key Ideas to Explore the other day, and it carries that same gentle patience, all drawn by hand, like letters from another century.
