North America’s thrips make up an extremely large family of insects.
Of the plant feeders alone, there are 264 species. And some of these species have a taste for palm trees, feeding on flowers and leaves by puncturing the surfaces to suck out sap. Thrips are not lethal to palms but the feeding of the adults can discolor and wilt leaves. In addition, in intensive infestations their unsightly black droppings can become noticeable on leaf surfaces.
