Insects are the most numerous species on Earth. In fact, there are over 200 million insects living on our planet right now. They are arthropods whose body is divided into parts and covered in exoskeleton that can grow into a shell. Insects also have specialized extremities, antennas, and often, wings. There is a wide spectrum of insect species, some of which feed on plants, while others feed on us and our property. Although we mostly see them as harmful, they are actually very important for maintaining the biological cycle of nature.
