Description: The introduced basswood thrips, Thrips calcaratus, is a recently recognized defoliator of American basswood in the Lake States. American basswood is a common understory tree throughout the northeastern United States, as well as an important, though often scattered, component of the forest overstory. Over the past several years, basswood stands in northern forests have suffered moderate to severe defoliation. Damage can resemble early spring frost injury, but examination of the newly expanding leaves reveals small, active insects.
