The document discusses the design of an insect's thorax, or middle section of the body. The thorax acts as the "engine room" as it contains the legs and wings. It has 6 legs and either 1 or 2 pairs of wings made of membranes supported by ribs and veins. Some insects, like locusts, migrate long distances while others only migrate short distances. The passage directs the reader to pages 27-28 to learn more about insect wings, migrations, and locust migrations.
