Arachnology
Arachnology is the science, scientific study of arachnids, which comprise spiders and related invertebrates such as scorpions, Pseudoscorpionida, pseudoscorpions, Opiliones, harvestmen, Tick, ticks, and mites. Those who study spiders and other arachnids are arachnologists. More narrowly, the study of spiders alone (Order (biology), order Araneae) is known as araneology. The word "wiktionary:arachnology, arachnology" derives from the Ancient Greek words , ''arachnē'', "spider"; and , ''-logia'', "the study of a particular subject". The greek word for "spider" itself refers to Arachne, the female protagonist of an ancient tale of the Greek mythology, Greek Mythology. Arachnology as a science Arachnologists are primarily responsible for biological classification, classifying arachnids and studying aspects of their biology. In the popular imagination, they are sometimes referred to as spider experts. Disciplines within arachnology include naming species and determining their phylog ...

Entomological Society Of Washington
The Entomological Society of Washington was organized on February 29, 1884 at a meeting called by three entomologists employed by the U.S. Department of Agriculture: Charles Valentine Riley, Eugene Amandus Schwarz, and Leland Ossian Howard, in Riley's home in Washington, D.C. Meetings have been held regularly since 1884. Several local locations were used as meeting places after it became impractical to hold meetings in members' homes, including the Washington Saengerbund Hall, the Cosmos Club, and the National Museum of Natural History of the Smithsonian Institution. The official seal of the society was adopted at the society's November 2, 1893 meeting and first appeared in March 1894. The insect featured in the seal is a winged male ''Rheumatobates rileyi'' Bergroth (Hemiptera, Gerridae), a water strider about 7 mm long including outstretched legs. Early members included Charles Valentine Riley, Eugene Amandus Schwarz, Leland Ossian Howard, August Busck, Adam Giede Böv ...

Biological Society Of Washington
Biology is the scientific study of life and living organisms. It is a broad natural science that encompasses a wide range of fields and unifying principles that explain the structure, function, growth, origin, evolution, and distribution of life. Central to biology are five fundamental themes: the cell as the basic unit of life, genes and heredity as the basis of inheritance, evolution as the driver of biological diversity, energy transformation for sustaining life processes, and the maintenance of internal stability (homeostasis). Biology examines life across multiple levels of organization, from molecules and cells to organisms, populations, and ecosystems. Subdisciplines include molecular biology, physiology, ecology, evolutionary biology, developmental biology, and systematics, among others. Each of these fields applies a range of methods to investigate biological phenomena, including observation, experimentation, and mathematical modeling. Modern biology is grounded i ...
