Theodore Pergande

Theodore Pergande (28 December 1840 – 23 March 1916) was a German-born American entomological pioneer known for his skills in rearing insects. He made careful observations on aphids and thrips and made collections and studies on North American ants, several of which, including the harvester ant ''Messor pergandei'' and the scale insect ''Parlatoria pergandii'', have been named after him.
