Cardamine: Lepidoptera possesses variations of the basic body structure which has evolved to gain advantages in adaptation and distribution. The head is shaped like a capsule with appendages arising from it. Adult mouthparts include a prominent proboscis formed from maxillary galeae and are adapted for sucking nectar.
They may have reduced mouthparts, while others have them modified for piercing and sucking blood or fruit juices.
Adult Lepidoptera has two immobile, multi-faceted compound eyes, and only two simple eyes or ocelli, which may be reduced. The three segments of the thorax are fused together. Antennae are prominent and besides the faculty of smell, also aid navigation, orientation, and balance during flight.
The wings, head parts of thorax, and abdomen of Lepidoptera are covered with minute scales, from which feature the order Lepidoptera derives its names, the word lepidos in Ancient Greek meaning “scale”.
