Paperback. Condition: New. Print on Demand. This book examines the red coloration produced by wet potassium cyanide on certain yellow species of Lepidoptera. The author of this work has succeeded in producing red blotches in various species of butterflies, including Callidryas eubule, Terias wise, and Catopsilia crocale, and theorizes that the wet cyanide reacts with yellow pigments in the butterflies' wings. The author also tested various other substances to determine if they would produce the same result. The work in this book contributes to our understanding of the chemical composition of Lepidoptera wings and provides a new way to study the relationship between chemicals and coloration in butterflies. The conclusions and methodology in this book will be of interest to entomologists and chemists alike.

Paperback. Condition: New. Print on Demand. This book presents a synopsis of the author's experiments in breeding hybrid moths. The experiments were conducted over seven years, and the author's goal was to determine the influence of the parents' species and sex on the offspring's sexual development. The author's findings have implications for our understanding of the role of genetics and the environment in the development of sexual characteristics.
