Wallace is a scientific publication written in the mid-19th century. The work delves into the study of butterflies, specifically the Papilionidæ family, emphasizing their variation, distribution, and the ecological factors influencing these phenomena. It is a detailed examination rooted in natural history, offering insights into the complexities of species and their adaptations. At the start of the text, Wallace presents an overview of the significance of studying variations and geographical distribution among butterflies, particularly focusing on the intricacies of the Papilionidæ family. He describes the unique beauty and diversity of these butterflies and how they serve as examples for studying biological variations and environmental influences. Notably, he discusses specific characteristics of their wings that aid in understanding variations, such as their coloration and structure, and he introduces various classifications of these butterflies based on their anatomical features and distribution across the Malayan region, setting the stage for a thorough exploration of this captivating group of insects.
