Document Summary

Most diverse hexapods, most species-rich of all animal groups, and there are 800,000 described. The other smaller groups of hexapods are springtails, protura, and diplura. There is the head, the thorax, and the abdomen. The abdomen of hexapods do not have appendages. Their eyes are made up of multiple lenses. Many have ocelli which is a simple eye. They are sensitive to light and they collect and focus light through a single lens. Not all insects have wings, which are called apterygote. They are a primitive group that lack wings. Some of these secondarily lost wings (lice, bed bugs, eas). Wings are not appendages, just extensions of the cuticle. Juveniles (nymphs) may share morphology and habitat of adult. Complete metamorphosis: wings develop all at once in a special stage called a pupa. Juvenile always had a di erent morphology and ecology than the adult. (caterpillar vs. butter y).
