The scales on butterfly wings are pigmented with melanins that can produce the colours black and brown. The white colour in the butterfly family Pieridae is a derivative of uric acid, an excretory product. [13] [40]: 84 Bright blues, greens, reds, and iridescence are usually created not by pigments but through the microstructure of the scales.

The basic colour of the wings is black, with a chain of white spots on the forewing and a large white or yellow area on the hindwing. The underside and the upperside of the wings in this species are very similar. The hindwings have wavy margins, with long tails. The thorax and the abdomen are black. [2]
The colour of butterfly wings is derived from tiny structures called scales, each of which have their own pigments. In Heliconius butterflies, there are three types of scales: yellow/white, black, and red/orange/brown scales. Some mechanism of wing pattern formation are now being solved using genetic techniques.
Its wings feature an easily recognizable black, orange, and white pattern, with a wingspan of 8.9–10.2 cm (3.5–4.0 in). [10] A Müllerian mimic, the viceroy butterfly, is similar in color and pattern, but is markedly smaller and has an extra black stripe across each hindwing.
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 ...
Pieris oleracea, or more commonly known as the mustard white, is a butterfly in the family Pieridae native to a large part of Canada and the northeastern United States. The nearly all-white butterfly is often found in wooded areas or open plains. There are two seasonal forms, which make it distinct from other similar species.
The silver-washed fritillary butterfly is deep orange with black spots on the upperside of its wings. It has a wingspan of 54–70 mm, with the male's being smaller and paler than the female's. The underside is green with a metallic gloss and broad silver bands which are partly curved, hence the name silver-washed. In the male the forewings are ...
