beetle Insect characterized by horny front wings that serve as protective covers for the membranous hind wings. These protective sheaths are often brightly coloured. Beetles are usually stout-bodied and their mouthparts are adapted for biting and chewing. They are poor fliers, but (like all insects) are protected from injury and drying up by an exoskeleton. Beetles are the most numerous of the insects. More than 250,000 species are known and new ones are still being discovered. They include scarab beetles, ladybirds, and weevils. Most feed on plants, some prey on small animals, including other insects, whereas others are scavengers. Beetles undergo complete metamorphosis. Their larvae (grubs) usually have three pairs of legs and distinct heads, usually dark in colour. Length: 0.5mm–6cm (0.02–6.3in). Order Coleoptera.
