Reece Ivan Sailer (1915- ) attended the University of Kansas, earning his Ph.D. in 1942. In that same year he joined the U.S. Department of Agriculture's Bureau of
Entomology and Plant Quarantine. Sailer subsequently held many assignments in the USDA, culminating in 1967, when he became chief of the Insect Identification and Parasite
Introduction Branch. His special interests are in the taxonomy of the subfamily heteroptera and the biology of Alaskan biting diptera.
