Scale insects are phytophagous, feeding by sucking plant juices through a set of stylets, and are found on nearly every part of their hosts. They are widely distributed throughout the world with the exception of the cold extremes of the Arctic and Antarctic. Host plant diversity is broad, although scales are not commonly found on ferns or mosses. This key was developed to support the scale-insect identification efforts of APHIS/PPQ port identifiers. A grant was provided through the USDA Center for Plant Health Science and Technology and the USDA Animal and Plant Health Inspection Service. A second infusion of funds came from the U S Department of Agriculture through Hilda Diaz-Soltero, USDA Invasive Species Liaison and Coordinator.
