Book excerpt: Excerpt from Thrips of Economic Importance in California Being so small, thrips are usually overlooked on plants. Their size ranges from %0 to inch in length. Some larger species measure inch. The thrips here discussed have two pairs of fringed wings, carried lengthwise over the back when not in use. A pair of antennae project forward from the head. The posterior end of the body is bluntly pointed. The male is usually smaller than the female. Besides flying and running rapidly, many adults have the ability to hop. The eggs are extremely small, bean-shaped, and very delicate (fig. 1, A). They are most commonly inserted in plant tissue, indicating their presence only by a tiny bump, and are rarely seen. The larval2 stage is soft-bodied, without Wings, and with other append ages much less developed. The newly hatched larvae (fig. 1, B) are very minute but when full-grown (fig. 1, 0) are about the size of the adult. The larvae are usually much more sluggish than the adults and feed in colonies. One molt occurs when the larva is about half-grown, and a sec ond when it is fully developed. The pupal or resting stage, though likewise soft-bodied, has wing stubs present. A third molt comes at the end of the prepupal stage (fig. 1, D). The last molt occurs when the adult emerges. The pupa (fig. 1, E) does not feed and, unless disturbed, does not move.
