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.
The wings, head parts of thorax, and abdomen of Lepidoptera are covered with minute scales, from which feature the order Lepidoptera derives its names, the word lepidos in Ancient Greek meaning "scale". Most scales are lamellar (blade like) and attached with a pedicel, while other forms may be hair like or specialised as secondary sexual ...
Scales on a luna moth (Actias luna) Generalized structure of a keeled, lanceolate scale from a jumping spider. Butterflies and moths - the order Lepidoptera (Greek "scale-winged") - have membranous wings covered in delicate, powdery scales, which are modified setae. Each scale consists of a series of tiny stacked platelets of organic material ...
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 ...
T. magellanus shows a blue-green sheen if viewed from an oblique angle.Troides magellanus and the much rarer T. prattorum, are noted for their use of limited-view iridescence: the yellow of the dorsal hindwings is modified by bright blue-green iridescence which is only seen when the butterfly is viewed at a narrow, oblique angle.
Lamellar armour is a type of body armour made from small rectangular plates (scales or lamellae) of iron, steel, leather , bone, or bronze laced into horizontal rows. Lamellar armour was used over a wide range of time periods in Central Asia , Eastern Asia (especially in China , Japan , Korea , Mongolia , and Tibet ), Western Asia , and Eastern ...
The individual scales used to construct Roman armour are called squamae. [5] [6] During Roman times, scale armour (lorica squamata) was a popular alternative to mail (lorica hamata) as it offered better protection against blunt force trauma. Hellenistic-Attic lamellar armour was also widely used in Middle Eastern empires, such as Persia and ...
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.
