What adaptations to the habitat have arisen in insects in the external structure?

There are millions of insect species on our planet. All of them have their own characteristics of the structure of the body and adaptation to the surrounding world. Consider the adaptations of only a few insects. Ants are small in size and have a special body structure. This allows them to calmly survive falls from any height. Grasshoppers have such a body structure that they are able to jump to a height that exceeds their size by tens and hundreds of times. The grasshopper can jump up to two meters in height. Other insects have their own adaptations.
