The body or 'blade' of a typical scale consists of an upper and lower lamina. The surface of the lower lamina is smooth whereas the structure of the upper lamina is structured and intricate. Scales are attached to the substrate by a stalk or 'pedicel'. [1] The scales cling somewhat loosely to the wing and come off easily without harming the insect.
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.
Micropterix aureatella, a micropterigid moth. The insect order Lepidoptera consists of moths and butterflies (43 superfamilies). [1] Most moths are night-flying, while the butterflies (superfamily Papilionoidea) are the mainly day-flying.

Pearlscale butterflyfish can grow to a standard length of 15 centimetres (5.9 in) with no discernible differences between males and females. The body is pearly white and the scales have black edges, giving the sides a more cross-hatched pattern instead of the clear chevrons in related species.
