Harrison Gray Dyar Jr. (February 14, 1866 New York City – January 21, 1929, Washington, D.C.) was an American entomologist.
He was a son of Harrison Gray Dyar and his wife Eleonora Rosella (née Hannum). Dyar graduated from Massachusetts Institute of Technology in 1889 with a Bachelor of Science degree in chemistry. He had begun to study insects as a young teenager, and soon after his graduation from college began publishing scientific papers about them, in particular moths of the family Limacodidae, starting a lifelong interest in entomology. He was awarded a Master of Arts degree in biology from Columbia University in 1894, with his thesis on the classification of Lepidoptera, and a Doctor of Philosophy degree in 1895, with his dissertation on airborne bacteria in New York City.
Dyar was a taxonomist who published extensively on moths and butterflies (Lepidoptera), mosquitoes (Diptera: Culicidae), and sawflies (Hymenoptera: Symphyta) during his working lifetime. His first job was as assistant bacteriologist of the College of Physicians and Surgeons of Columbia University from 1895 to 1897. From 1897 until his death he was honorary custodian of Lepidoptera at the U.S. National Museum, Washington, D.C. Dyar was independently wealthy and for a major part of his 31 years at the USNM he worked without compensation; his independence also made it possible for him to travel and collect extensively within North America.
