Beetles are insects that form the order Coleoptera (), in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described arthropods and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species.

鞘翅目（Coleoptera）是昆蟲綱中最大的目，包括各種甲蟲。目前全世界的甲蟲，約182科，約有35萬種，超過全動物界其他所有目的總和。除了在海洋和極地之外，任何環境都可以發現甲蟲。甲蟲一般都有外骨骼，前翅為硬殼，通常可以覆蓋身體的一部分以及保護後翅；前翅不能拿來飛行。一些種類已經有部分的種類喪失飛行能力，如步行蟲和象鼻蟲。甲蟲為完全變態的生物（卵、幼蟲、蛹、成蟲）
