Besides providing insulation, dark patterns on wings provided by dark colour scales would allow sunlight to be absorbed and thus probably have a role to play in thermoregulation. Bright and distinctive colour patterns in butterflies which are distasteful to predators help communicate their aposematism (toxicity or inedibility) thus preventing a ...
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 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 colourful patterns on many butterfly wings tell potential predators that they are toxic. Hence, the genetic basis of wing pattern formation can illuminate both the evolution of butterflies as well as their developmental biology. The colour of butterfly wings is derived from tiny structures called scales, each of which have their own pigments.
Moths have larger scales on their wings which makes them look more dense and fluffy. Butterflies on the other hand possess fine scales. This difference is possibly due to the need for moths to conserve heat during the cooler nights, or to confound echolocation by bats, whereas butterflies are able to absorb sunlight .
The Morpho Menelaus' characteristic iridescent wings has a unique wing structure. The ground scales are covered by a set of longitudinal ridges, and within the ridges are layers of lamella. [12] Because the size of the microstructure is the same as the wavelength of light, the layers in the wings react strongly with visible light. [2]

Transition of scales color on a butterfly wing (30x magnification). The two pairs of wings are found on the middle and third segment, or mesothorax and metathorax respectively. In the more recent genera, the wings of the second segment are much more pronounced, however some more primitive forms have similarly sized wings of both segments.
