Thysanoptera, Thrips


[R] Order of hemimetabolous insects with 2 or 3 inactive pupa-like stages; body small and slender; antennae short; mouthparts asymmetrical and piercing, forming a mouth-cone; tarsi 1- or 2-segmented, each with a terminal bladder; wings very narrow with hair-like fringes. There are two suborders: the Terebrantia, which have a saw-like ovipositor, and the Tubulifera.
Thrips suck out the contents of external cells of leaves, causing the later to become silvery. They are also vectors of viruses and contaminate plants with frass.
Includes a family of important pests: the Thripidae.
