# Florence E. Bemis

Florence Eugenie Bemis (1861?–?) was a late 19th and early 20th century American entomologist and expert in whiteflies.

## Scientific career

Bemis worked at Stanford University in the laboratory of entomologist Vernon Lyman Kellogg and in the field collecting specimens and making biological observations. She studied insects of the Aleyrodidae family, which are known as whiteflies and at the time were also called mealy-winged flies for the waxy white secretion that covers their wings. In 1904, she published a long monograph on a subset of these insects, entitled The Aleyrodds, or Mealy-Winged Flies, of California, with References to Other American Species. In it she described 19 new species of whiteflies found in California, together with a catalogue of whitefly species found elsewhere in America. Although she placed them all in the genus Aleyrodes, many of them have since been moved into other whitefly genera, including Aleuropleurocelus, Aleuroparadoxus, Aleurothrixus, Pealius, Tetraleurodes, and Trialeurodes. Her work is credited with greatly advancing knowledge of California species of whiteflies.

The taxonomic genus Bemisia within the family Aleyrodidae, comprising some of the whiteflies, is named in her honor.
