Identifying characters Mouthparts form a coiled tube (proboscis)beneath the head and adapt for sucking Antennal type: Butterflies:knobbed or hooked at tip Moths:thread-like,spindle-shaped,or feather- like Adults have two pairs of membranous wings,front wings large,triangular;hind wings fan-shaped Body and wings covered with small,overlapping scales

Identifying characters ❖ Mouthparts form a coiled tube (proboscis) beneath the head and adapt for sucking ❖ Antennal type: ❖ Butterflies: knobbed or hooked at tip ❖ Moths: thread-like, spindle-shaped, or feather￾like ❖ Adults have two pairs of membranous wings, front wings large, triangular; hind wings fan-shaped ❖ Body and wings covered with small, overlapping scales

The larvae of Lepidoptera are usually eruciform, each of the thoracic segments bears a pair of legs,and abdominal segments 3-6 and 10 usually bear a pair of prolegs. Larvae have chewing mouthparts ■ 四句顺口溜来记忆： ■虹吸口器鳞翅目， ■四翅膜质鳞片覆； ■蝶舞花间蛾扑火， ■幼虫多足害植物
