The name is derived from Ancient Greek λεπίδος (scale) and πτερόν (wing). [1] The Trichoptera (caddisflies) which are a sister group of the Lepidoptera have scales, but also possess caudal cerci on the abdomen, a feature absent in the Lepidoptera. [2] Beetles of family Dermestidae also commonly have scales. [3]
Lepidopterology (from Ancient Greek λεπίδος (lepídos) 'scale' πτερόν (pterón) 'wing' and -λογία [1]) is a branch of entomology concerning the scientific study of moths and the two superfamilies of butterflies. Someone who studies in this field is a lepidopterist or, archaically, an aurelian.
Scales play an important part in the natural history of Lepidoptera. Scales enable the development of vivid or indistinct patterns which help the organism protect itself by camouflage, mimicry, and warning. Besides providing insulation, dark patterns on wings allow sunlight to be absorbed and are probably involved in thermoregulation.
The moth's wings lack the large amount of scales found in most other lepidopterans, particularly in the centralized regions, making them appear clear. It loses the scales on its wings early after the pupa stage by its highly active flight tendencies. Hemaris diffinis is an excellent bumblebee mimic.
The colours on the Madagascan sunset moth's wings are produced by the conjunction of two optical phenomena: An air-cuticle multilayer in the scales creates optical interference. Each scale contains cuticle layers with randomly located blocks of cuticle that hold them in place and maintain an air gap between them.
The brilliant blue color in the butterfly's wings is caused by the diffraction of the light from millions of tiny scales on its wings. It uses this to frighten away predators, by flashing its wings rapidly. The wingspan of the blue morpho butterfly ranges from 7.5–20 cm (3.0–7.9 in).
