Theodore Cockerell

Theodore Dru Alison Cockerell was a British and American entomologist and systematic biologist who published nearly 4,000 papers, some of them only a few lines long. Cockerell's speciality was the insect order Hymenoptera, an area of study where he described specimens from the United States, the West Indies, Honduras, the Philippines, Africa, and Asia. Cockerell named at least 5,500 species and varieties of bees and almost 150 genera and subgenera, representing over a quarter of all species of bees known during his lifetime. In addition to his extensive studies of bees, he published papers on scale insects, slugs, moths, fish scales, fungi, roses and other flowers, mollusks, and a wide variety of other plants and animals.
