How many legs do insects have?

Insects are characterized by having six legs, which is a defining feature of their class, Insecta. This hexapod design is fundamental to their anatomy, providing them with a range of mobility and adaptability to various environments. The six legs are typically divided into three pairs, with each pair serving different functions such as walking, jumping, or climbing. This structural uniqueness helps distinguish insects from other arthropods, such as arachnids, which have eight legs, or crustaceans, which may have more legs. Understanding this basic anatomical characteristic is crucial for anyone studying entomology or pest control, as it helps in the identification and management of insect pests.
