Document Summary
No real distinction between butterflies and moths. However, in general, butterflies are day flying, whilst moths fly mainly at night. Butterflies are usually slimmer bodied, and have thin antennae with distinct clubs at the end. Moths have antennae of various designs, from thin and tapering to wide and "feathery". Feathery antennae are found in male moths, and help them to sniff out females! 4 wings, 6 legs, 2 antennae and a body divided into 3 sections feed through a specialised tube formed by some of the mouthparts, known as a proboscis. Have two pairs of wings, a large fore pair and a smaller hind pair. These wings are held together by a series of hooks (called a frenulum) and may appear like a single pair to the naked eye. Prominent antennae, generally with nine or more segments and biting mouthparts.
