Butterfly wing at different magnifications reveals microstructured chitin acting as diffraction grating. Main article: Structural coloration While many animals are unable to synthesize carotenoid pigments to create red and yellow surfaces, the green and blue colours of bird feathers and insect carapaces are usually not produced by pigments at ...
The wings of Lepidoptera are minutely scaled, which gives the name to this order; the name Lepidoptera was coined in 1735 by Carl Linnaeus for the group of "insects with four scaly wings". It is derived from Ancient Greek lepis (λεπίς) meaning "(fish) scale" (and related to lepein "to peel") and pteron (πτερόν) meaning "wing". [37]
The blue copper, also known as Lycaena heteronea, is an American butterfly that belongs to the gossamer-winged family. The butterfly is named so because of the bright blue hue of the upper side of the males' wings. Females are brown on their upper side. Both sexes are white with black spots on the underside of the wings.
The wing on the left is typical of a male Lexias pardalis butterfly, and the wing on the right is typical of. Right away you can tell this isn't your typical butterfly, but those mismatched wings ...
The wing colors vary with viewing angle, a phenomenon referred to as structural color. [2] In the female, the dorsal side is more camouflaged while the male presents with a vibrant blue. [11] In the male, the outer layer of the cover scales are long and narrow (250 μm × 50 μm), 2 μm apart, and parallel to the wing plane. [11]
Zerene eurydice, the California dogface butterfly, belongs to the family Pieridae and is a sister genus to Colias. [2] The Zerene eurydice and the Colias both share the "characteristic of having yellow-orange and black wing coordination." [3] Additionally the,"Colias and Zerene eurydice males have bright UV patterns on their wings."
The butterfly is host-specific on the Kincaid's lupine, which it relies on for reproduction and growth. The male and female can be identified by their difference in wing color. The Fender's Blue Butterfly was added to the endangered species list in January 2000, but as of February of 2023, has been reclassified as "threatened". [3]
A male-only pattern of coloration due to this iridescence is seen exclusively under ultraviolet light, since females absorb light on the ultraviolet spectra. The presence of exclusively leucopterin in female wings explains the lack of iridescence in female common brimstones, since leucopterin absorbs only in the ultraviolet range. [ 7 ]
