Keeled scales of a colubrid snake (banded water snake; Nerodia fasciata) In zoology, a scale (Ancient Greek: λεπίς, romanized: lepís; Latin: squāma) is a small rigid plate that grows out of an animal's skin to provide protection. In lepidopterans (butterflies and moths), scales are plates on the surface of the insect wing, and provide ...
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.
Photographic and light microscopic images: Zoomed-out view of an Aglais io. Closeup of the scales of the same specimen. High magnification of the coloured scales (probably a different species). Electron microscopic images: A patch of wing: Scales close up: A single scale: Microstructure of a scale: Magnification: Approx. ×50 Approx. ×200 × ...
Illustrates both the structure of a butterfly wing at various scales of magnification, and the relative merits and disadvantages of light vs electron microscopy (for possible later inclusion in microscopy-related articles). All images above current standards. Please review this with fairness towards the contributors rather than the nominator.
A Lepidoptera specimen drawer in a museum collection in Poland Another Lepidoptera specimen drawer in a museum collection in Poland. Lepidopterology (from Ancient Greek λεπίδος (lepídos) 'scale' πτερόν (pterón) 'wing' and -λογία [1]) is a branch of entomology concerning the scientific study of moths and the two superfamilies of butterflies.
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 ...
Olfactory receptors (scales and holes) on the antenna of the butterfly Aglais io, electron micrograph. Olfactory receptors on the antennae bind to free-floating molecules, such as water vapour, and odours including pheromones.
These scales give butterfly wings their colour: they are pigmented with melanins that give them blacks and browns, as well as uric acid derivatives and flavones that give them yellows, but many of the blues, greens, reds and iridescent colours are created by structural coloration produced by the micro-structures of the scales and hairs.
