When stonefly reached the wing, it was already obvious. If the insect has matured for a few days before feeding, it will climb to the plant, hang down its body, wait for a while, and the adult will emerge. The muscles of the hind legs are strong, the exoskeleton is hard, and the receptors of the head, abdomen and legs can feel touch. Among the taste organs, the antenna has the sense of smell. There is a layer of tympanic membrane at the base of abdominal segment or tibial segment of forefoot, which is in charge of hearing. The compound eye is responsible for vision and the single eye is responsible for light perception. The hind limbs and legs are thick, and there is no habit of clustering and migration. They often live in one place, generally scattered activities, eating plants. Insects hatch from eggs to nymphs and become adults after eclosion. They hibernate in the soil without pupae and hatch from eggs to nymphs in early summer. Nymphs have no wings, and their appearance and lifestyle are similar to those of adults. For every generation. Adults lay eggs in the soil layer, forming blocks and being wrapped by capsules. Overwintering in the soil layer with eggs. Nymphs are 5 years old. Adults are good at flying, and nymphs spread mainly. Mulberry thrips do not have the habit of clustering and migration, and often live in one place, generally scattered activities, feeding on plants. This insect is incomplete. It hatches from an egg to a nymph and becomes an adult after eclosion. It overwinters in the soil without pupae, and hatches from eggs to nymphs in the early summer of the following year. Nymphs have no wings, but it is beneficial to apply wax powder slightly when it rains on sunny days. Shorter than the body is because of the abdomen. The round tail of the abdominal tube can continue to live round or live alone. Its shape and lifestyle are similar to those of adults, and adults usually emerge every year. Born with wings, they lay eggs for the winter. Most species have the same host cycle, and there is no transfer between woody and herbaceous hosts, but only between the same host plants. Sometimes there are newly unearthed wings, which gradually taper towards the end, sometimes at the middle or end, most species are round, rarely oval, and have the same host sensory circle.
