Butterflies differ from moths in several ways: their wings will typically rest horizontally (flat) and the forewings are not hooked. The wings are also covered with overlapping scale-liked hairs which, when viewed from afar, present the vibrant patterns we commonly associate with butterflies. These patterns serve multiple purposes: protection from predators, courtship and body temperature regulation. There are two pairs of wings called the forewing and the hindwing due to their relative positioning along the thorax. Their antennae are "clubbed" at their tips and their habit is generally centered around day time flying, passing from flower-to-flower in search of food. They have a tongue-liked appendage called a "proboscis" which is rolled up when not in use and rolls out when it comes time to feed, allowing the butterfly to reach deeply into a flower blossom.
