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.

The scales are highly curved, which creates inter-scale reflection. This mechanism is unusual among Lepidoptera. The proximal part of each scale is almost flat; the scale then gradually curves up and then steeply bends down at the distal end, covering the proximal part of the next row of scales.
Androconial spot on the hind wing of the African butterfly Bicyclus anynana. The center pupil of the so called anterior "eyespot" on the fore wing of the African butterfly Bicyclus anynana scale. The bush brown is a small brown butterfly with a wingspan of 35–40 mm for males and 45–49 for females.

The wide-angle blue reflection property can be explained by exploring the nanostructures in the scales of the morpho butterfly wings. [9] These optically active structures integrate three design principles leading to the wide-angle reflection: Christmas tree-like shaped ridges, alternating lamellae layers (or "branches"), and a small height ...
