Order Thysanoptera

Thrips are tiny insects, with or without wings, and are rarely over 1/8 inch long. They have rasping-sucking mouthparts, which they use to rasp the surface of leaves and suck up the juice as it oozes out. Metamorphosis is gradual, the life stages being the egg, nymph, prepupae, pupae and adult. Thrips are commonly found on many plants, including gladiolus, onions and greenhouse crops.
