Insects make up 73% of the world's living organisms and have bodies divided into three parts - head, thorax, and abdomen. They go through life stages of egg, larva, pupae, and adult. Insects can eat using mandibles, tube-like mouthparts, or sponge-like mouthparts and move by flying, crawling, jumping, or swimming. While their communication is rudimentary, some argue insects coordinate behaviors through visual cues or behaviors like the bee dance.
