By Benjamin Dann Walsh

Book Overview

On Dimorphism In The Hymenopterous Genus Cynips is a scientific book written by Benjamin Dann Walsh and published in 1864. The book focuses on the genus Cynips, which is a group of parasitic wasps that are known for their ability to induce galls on plants. Walsh's research in this book centers around the phenomenon of dimorphism, which refers to the existence of two distinct forms of individuals within a species. Walsh's observations and experiments in this book reveal that Cynips exhibits two forms of females: one that is wingless and reproduces asexually, and another that has wings and reproduces sexually. He also notes that the winged form of female Cynips is similar in appearance to the males of the species. The book goes into great detail about the anatomy, behavior, and life cycle of Cynips, and includes numerous illustrations and diagrams to aid in understanding.Overall, On Dimorphism In The Hymenopterous Genus Cynips is a significant contribution to the field of entomology, as it sheds light on the complex reproductive strategies and adaptations of these fascinating parasitic wasps.With An Appendix, Containing Hints For A New Classification Of Cynipidae And A List Of Cynipidae, Including Descriptions Of Several New Species, Inhabiting The Oak-Galls Of Illinois.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
