Blue Wing Teal

Myscelia ethusa

Myscelia ethusa, the Mexican bluewing or blue wing, is a butterfly of the family Nymphalidae. The species was first described by Louis Michel François Doyère in 1840. It is found from Colombia north through Central America to Mexico. Strays can be found up to the lower Rio Grande Valley of Texas in the United States.

Wing

A wing is a structure which produces both lift and drag while moving through air. Wings are defined by two shape characteristics, an airfoil section and a planform. Wing efficiency is expressed as lift-to-drag ratio, which compares the benefit of lift with the air resistance of a given wing shape, as it flies. Aerodynamics includes the study of wing performance in air.

Blue

Blue is one of the three primary colours in the RGB (additive) colour model, as well as in the RYB colour model. It lies between violet and cyan on the spectrum of visible light. The term blue generally describes colours perceived by humans observing light with a dominant wavelength between approximately 450 and 495 nanometres. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called the Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective.

Teal

Teal is a dark cyan color. Its name comes from that of a bird, the Eurasian teal which has a similarly colored stripe on its head. The word is often used colloquially to refer to shades of cyan in general.
