Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Physical Study of the Firefly Aside from this utilitarian question, there are others of equal importance. For example, we know that closely related species of fire ies emit differently colored light, variously described as blue, green, orange, etc. IS this color variation a subjective phenomenon, resulting from the variation in color sensibility of the eye with variation in intensity, * or is it an Objective reality? If the latter, then what are the laws governing the light emission? It is almost too much to hope to solve this problem in the near future, but it seems possible to settle definitely the question whether or not the light differs in composition and hence is blue, green, or orange, as observed. This knowledge is Obtained from the spectral energy curves of the light from various fire ies, to be described presently. Experimenters have become so accustomed to thinking of the artificial production of light as being accompanied by a large amount of invisible radiation that no experiments would be complete without a repetition of Langley's search for infra-red radiation. Accordingly this question has also been given attention in this paper. In View of the doubt in many investigators' minds as to whether the color of the light from the fire y is due to a variation in intensity rather than to an actual variation in composition, it seemed worth while to attempt to settle the question by making a thorough study of the light emitted by various species of this insect. Accordingly, the photographic work was continued for about four weeks, during which time 152 photographic exposures were made, on two spectrometers differing widely in dispersion, the time of exposure varying from 30 seconds to 5 hours. The time consumed in actual photography, in holding the insects on the spectrometer slit, was over 56 hours. The histological data is introduced for clearness in discussing the present work, as well as its bearing upon the whole subject. It permits also a discussion of the plausibility of the functions assigned to certain parts of the photogenic organs as viewed from a physical standpoint and more especially from the optical properties of materials.

This book was released on 2017-03-01 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive firefly guide for eastern and central North America ever published. It is written for all those who want to know more about the amazing world of lightning bugs and learn the secrets hidden in the flash patterns of the 75+ species found in the eastern and central U.S. and Canada. As an independent researcher working with numerous university teams, naturalist Lynn Frierson Faust, “The Lightning Bug Lady,” has spent decades tracking the behavior and researching the habitats of these fascinating creatures. Based on her twenty-five years of field work, this book is intended to increase understanding and appreciation of bioluminescent insects while igniting enthusiasm in a fun and informative way. Species accounts are coupled with historical background and literary epigraphs to engage and draw readers young and old into the world of these tiny sparklers. A chart documenting the flash patterns of the various species will aid in identification. Clear photos illustrate the insects’ distinguishing physical characteristics, while habitats, seasonality, and common names are provided in clear, easy-to-understand yet scientifically accurate language. The guide will be welcomed by everyone who wants to learn more about fireflies' and glow-worms' unique traits and about their fragile niche in the ecosystem. FEATURES Over 600 color photographsDetailed accounts and anatomical diagrams of 75+ species, as well as aids in distinguishing between similar speciesA first-of-its-kind flash-pattern chart that folds out on heavy-weight paper • Extensive scientific details written in an understandable and engaging wayColorful, common names—Twilight Bush Baby, Shadow Ghosts, and Snappy Syncs, and more—for easy species identification based on flash patternsTips on ideal sites and times of year for firefly watchingConservation-oriented approach
