Saturday, 30 January, was the birthday of Charles De Geer, a Swedish entomologist born in 1720. De Geer was an ardent observer of insects, describing 1446 species. He was known for the accuracy of his drawings and was responsible for subdividing the Hemiptera, or "true bugs," which include such species as the firebug and green stinkbug. De Geer also raised awareness about the role of insects as pollen carriers.
