Physical Description

Thrips are slender, elongate in their bodies and the head is elongate as well. They range in color from black to dark brown to tan to yellowish. They are usually hypognathous. The mouthparts consist of a single stylet on the mandible and two stylets on the maxilla. These form a feeding tube. Thrips have small or large compound eyes, and three ocelli are present in fully winged forms. The abdomen consists of eleven segments, whereby ten segments are visible. In some species, an ovipositor is present on the female. Forewings and hindwings are similar. They are narrow and have a setal fringe. The short antennae are in four to nine segments. The legs are short and have a retractile bladderlike organ. When inflated, this organ provides adhesion to smooth surfaces.

Range length: 0.5 to 15.0 mm.

Other Physical Features: ectothermic ; bilateral symmetry

Sexual Dimorphism: sexes alike; female larger
