Alfred Goldsborough Mayer's 1897 article explores the coloration of lepidopteran wings. He details meticulous experiments investigating pigment and structural colors, arguing that the latter, caused by physical wing structures like scales and ridges, produce iridescent and metallic hues. Mayer examines the influence of temperature and humidity on pupal development and resultant wing color, finding that these factors can significantly alter color patterns. He also delves into the protective value of coloration, noting mimicry and camouflage strategies, and theorizes about the physiological processes underlying pigment formation. Ultimately, Mayer connects color variations to environmental influences and adaptation, suggesting the importance of physical laws and evolutionary pressures in shaping lepidopteran wing coloration.
Alfred Goldsborough Mayer's 1897 work, "The Colour and Colour-Patterns of Moths and Butterflies," meticulously explores the intricate world of lepidopteran coloration, delving into both its physical basis and its potential evolutionary significance. Mayer's study, published in the prestigious Proceedings of the Boston Society of Natural History, represents a thorough investigation conducted with the scientific rigor of the late 19th century. He systematically categorizes the diverse array of colors observed in these insects, differentiating between pigmentary colors, which arise from chemical compounds within the scales, and structural colors, produced by the physical interaction of light with the intricate microstructures of the wing scales. This latter phenomenon, involving refraction, diffraction, and interference, fascinated Mayer, who meticulously described the scale architecture responsible for iridescent hues and metallic sheens.
He meticulously documented the specific colors observed in various species, providing detailed descriptions of the patterns formed by the arrangement of differently colored scales. His work goes beyond mere cataloging, however, venturing into the adaptive significance of these colors and patterns. He considers the roles of camouflage, mimicry, and sexual selection in shaping the evolution of lepidopteran wing coloration, proposing hypotheses about the selective pressures that might have driven the development of specific patterns. He discusses how certain color patterns might provide protection from predators through either concealment or by mimicking unpalatable species, thereby deterring attack. Conversely, he also acknowledges the potential role of vibrant colors in attracting mates, highlighting the complex interplay between natural and sexual selection.
Mayer’s experimental approach is evident throughout his study. He describes meticulously designed experiments involving the manipulation of butterfly wings, for example, by removing scales or applying chemicals, to elucidate the origins of specific colors and their responses to different stimuli. This hands-on investigation provides concrete evidence to support his hypotheses about the physical and chemical properties underlying the observed color phenomena. The accompanying illustrations, meticulously rendered, serve to further clarify his observations and arguments, offering a visual complement to the detailed textual descriptions. They showcase the remarkable diversity and intricacy of butterfly and moth wing patterns, demonstrating the sheer complexity of the subject under investigation. In essence, Mayer's work represents a significant contribution to the scientific understanding of lepidopteran coloration at the turn of the 20th century, laying the groundwork for future research in this field by combining detailed observation, rigorous experimentation, and insightful interpretation.
