Excerpt from Additional Observations on Sexual Selection in Spiders of the Family Attidæ: With Some Remarks on Mr. Wallace's Theory of Sexual Ornamentation
On seeing the female, which he does when eight or ten inches away, he approaches her slowly; when within three or four inches lie-begins to sway from side to side by bending all the legs on'on'e side and extending the opposite ones, and then reversing the process, at the same time advancing. The palpi are stretched out sideways, thus exposing the blue clypeus. As he moves, the female eyes him attentively and seems to be interested in his display. When quite near her he raises the first legs and holds them perpendicularly upward, and then, as he comes closer, lowers them so as to touch her. This seems to frighten her, and she runs Off. The whole performance is repeated six or eight times before she finally yields, either to his boldness and persistence, as Mr. Wallace would haveit, or to the combination of these qualities with grace and beauty.

Paperback. Zustand: New. Print on Demand. This book delves into the debate surrounding Charles Darwin's theory of sexual selection, with a particular focus on the mating behaviors of spiders. The author provides substantial evidence to support Darwin's theory, arguing against alternative explanations put forth by Alfred Russel Wallace. Throughout the book, the author explores the intricate courtship rituals of various spider species, examining how males utilize physical adornments, such as bright colors, leg modifications, and facial ornamentation, to attract females. Countering Wallace's suggestion that these traits are merely byproducts of the male's vigor and not chosen by the female, the author demonstrates that female spiders actively select mates based on these displays. This captivating exploration of sexual selection in spiders adds to our understanding of the diversity and complexity of mating behaviors in the animal kingdom.
