Beetles (order Coleoptera) are instantly recognizable by their hard, protective forewings (elytra) that shield their delicate flying wings and abdomen. With over 350,000 known species, they make up the largest group of insects on Earth. They feature three main body parts, six legs, and a tough exoskeleton.These miniature "tanks" are incredibly adaptable and can be found almost anywhere on the globe, from bustling gardens to dense forests. Beetles boast diverse diets; some are voracious predators, others feed strictly on plants, and many act as vital scavengers that recycle nutrients into the soil.
