Butterflies are adult flying stage of certain insects belonging to an order or group called Lepidoptera. Moths also belong to this group. The word "Lepidoptera" means "scaly wings" in Greek. This name completely suits the insects in this group because their wings are covered with thousands of tiny scales overlapping in rows. The scales, which are arranged in colorful designs unique to every species, are what give the butterfly its beauty. Like all other insects, butterflies also have six legs and three main body parts: head, thorax (chest or mid section) and abdomen (tail end). They also have two antennae and an exoskeleton.
