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.
Unusual works like the Butterfly Fauna of Ceylon (1942) by Lionel Gilbert Ollyett Woodhouse (1888–1965) and Moths and Butterflies of the United States East of the Rocky Mountains (1900) by Sherman F. Denton made use of butterfly wing-prints where the illustrations incorporated the scales of the wings. [4]
The male specimen was a mostly gray and white with a “few yellowish-brown scales” toward the center of its wings, Vargas said. Its forewing measured about 0.4 inches.
Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP-ih-DOP-tər-ə) or lepidopterans is an order of winged insects which includes butterflies and moths.About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, [1] [2] making it the second largest insect order (behind Coleoptera) with 126 families [3] and 46 superfamilies ...
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.
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]
