A bug’s mouth parts form a complex stinging and sucking device. In broad outline, it consists of a long, thin straw which, when not in use, is located in a sheath formed by the extended lower lip. Some bugs do not have wings; however, most ticks have two pairs. The rear wings are clear flying wings, while the front pair is leathery elytrons. Bugs lay eggs and young bugs, called nymphs resemble adults except for size and that their wings are not yet functional.
