An Enquiry Into The Cause And Extent Of A Special Color Relation Between Certain Exposed Lepidopterous Pupoe is a scientific book written by Edward Bagnall Poulton and published in 1887. The book is focused on the study of the coloration of Lepidoptera pupae, which are the developmental stage between larvae and adult butterflies or moths. Poulton investigates a special color relation that occurs between certain exposed pupae and their surroundings, which he calls ""protective coloration."" He explores the causes and extent of this color relation, examining various factors such as the pupae's habitat, the types of predators present, and the pupae's own coloration. The book includes detailed descriptions and illustrations of various Lepidoptera pupae, as well as scientific observations and data analysis. This book is a valuable resource for scientists, researchers, and anyone interested in the study of Lepidoptera coloration and protective adaptations.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
