Produktbeschreibung
Excerpt from Bulletin the North American Clear-Wing Moths of the Family Aegeriidae, 1877 George Paul Engelhardt (1871-1942) devoted most of his life to nature studies, but his chief entomological interest for over 40 years was the lepidopterous family Aegeriidae. His approach to the study of this group was that of the field biologist and began with rearings of local species in the neighborhood of Brooklyn, N. Y. Thereafter, as he built his extensive collection, he followed through with biological and ecological studies and made trips to the several sections of the United States, Alaska, Europe, Central America, and British Columbia, collecting and rearing from larvae and observing the behavior and peculiar habits of the species of these regions. He thereby got an accurate and comprehensive biological picture of the American aegeriid fauna, discovered many new life histories, and was able to establish the more intimate relationships of several supposedly different species through their host-plant associations and the discovery of intergrading forms. His final objective was a monograph of the American Aegeriidae and a reclassification of that group upon the basis of structural characters coordinated with biological habits and host associations. This objective was only partially realized, for he died before he could prepare more than the preliminary draft of his manuscript. For many years close collaboration existed between Mr. Engelhardt and the lepidopterists of the Bureau of Entomology and Plant Quarantine, whose headquarters are at the United States National Museum. His collection and manuscripts were willed to the National Museum, and it was his hope that that institution would publish his work. During the years 1939, 1940, and 1941, Mr. Engelhardt spent his winters at Washington working out, in collaboration with August Busck, the generic classification and incorporating the genitalic characters of the moths into a revised classification. At Mr. Busck´s suggestion, drawings of male and female genitalia were made by Mrs. Mary F.Benson, of the Bureau of Entomology and Plant Quarantine, for the proposed paper. Mr. Engelhardt had planned his work on broad lines and had hoped to include larval and pupal characters in the definitions of categories but as the immature stages of several of the genera were still unknown this was not feasible; so at his request I prepared a short description of the larval and pupal characters of the family. When the manuscript was examined after Mr. Engelhardt´s death it was found to be substantially complete for the treatment of the species and their genera, but, as stated above, it was only a preliminary draft, with no introduction and no general discussion of the biology or previous systematic treatments of the group as a whole.
