Flower thrips are chronic pests of both southern highbush and rabbiteye blueberries in the southeastern United States. Flower thrips are small insects, less than 1.5 mm long (0.06 inches), with slender bodies usually yellow to orange in color. Females are typically larger than males. Adult thrips have long narrow wings fringed with fine hairs. Adults and immatures, called nymphs, have rasping-sucking mouthparts, which they use to extract sap from plant cells. Immatures look like the adults except they are smaller and have no wings.
