Andrew Delmar Hopkins (August 20, 1857 – September 22, 1948) was an American entomologist of the late 19th and early 20th centuries. Though self-taught, his scientific understanding of forest entomology was exceptional. He received an honorary doctorate from West Virginia University and in 1902 he went to work for the US Department of Agriculture. He was subsequently named head of the newly created Division of Forest Insect Investigations. He became a specialist in the bark beetle family Scolytidae, especially the genus Dendroctonus, species of which are the most destructive insects in coniferous forests of North America. His taxonomic monographs on these beetles are classics. He proposed the Law of Bioclimatics and he also developed the Hopkins Notes and Records System, a system he brought into the federal government when he first came to work for the Division of Entomology in the late 1890s. Hopkins’ research is one of the cornerstones of entomology on the North American continent and he is often referred to as the “father of North American forest entomology.”
