No, scorpions are not insects. They belong to a separate group of arthropods called arachnids, which includes spiders, ticks, mites, and harvestmen. Unlike insects, which have six legs, scorpions have eight legs. They also have two additional appendages called pedipalps, which they use for capturing and manipulating prey. Another distinctive feature of scorpions is the presence of a long, curved tail that ends with a venomous stinger.
Insects, on the other hand, are characterized by having six legs, three body segments (head, thorax, and abdomen), and usually a pair of wings. Examples of insects include bees, butterflies, ants, and beetles.
While scorpions and insects are both arthropods, they belong to different taxonomic groups within the arthropod phylum.
