Beetles are found in just about every habitat. Most species live on plants, others tunnel or burrow, some swim. Beetles have four different stages in their life cycle. Adult female beetles mate and lay eggs, which hatch into a larval stage that is wingless and can be identified by their worm-like body with six legs and a hard head. The larva feed, grow and eventually change into a pupal stage, where they are covered with a leathery skin and do not move or feed. Eventually the pupa transforms into an adult beetle.

• Beetle bodies tend to be very solid and tough and have chewing mouthparts and often have powerful jaws.
• Adult beetles have modified wings: the first pair of wings is small and very hard, and acts as a protective covering for the second pair of wings.
• Most adult beetles are brown or black, but some are very brightly colored.
