How Do Butterflies Change Colors

Butterflies possess some of the most striking color displays found in nature. As they fly from flower to flower gathering nectar, their brightly colored wings seem to shimmer and change colors before your eyes. But with structural colors, the angle at which light hits the wings as they flutter will cause the color to change - a shimmering effect we call iridescence.

Lepidoptera is an order of insects that include butterflies and moths. There are possibly over 20,000 species of butterflies in the world, out of which some 750 are found in the US. Butterflies and moths are masters of disguise, able to copy animal faces, rolled-up leaves and even snakes.

Welcome to the kaleidoscopic world of the butterfly wing. How do butterflies and moths (known collectively as Lepidoptera) make use of their vibrant wing patterns? Why are some species experts. Butterfly wings come in an amazing assortment of colors and patterns.

Aside from being beautiful, they also serve a purpose. They can help butterflies find a mate, blend in with their surroundings, or absorb heat. In toxic species, bright colors warn predators to stay away.

Read on to learn what makes these colors and what genes have to do with it. Researchers have been intrigued for centuries by how butterflies can generate the breathtakingly beautiful patterns and colors on their wings. The genetic code in the cells of developing butterfly wings actually dictates the specific arrangement of color on the wing's scales.

Butterflies, with their delicate patterns and bright colours, are the most popular of all insects. But beyond their beauty, what can the study of their colours tell us about the lifestyle and evolution of these fascinating insects? The colour patterns on their wings, formed by the juxtaposition of tiny scales, are extremely diverse: while many butterflies are brightly coloured, some are much. Whether shiny gold or iridescent blue, colors help butterflies camouflage and communicate.

Butterflies get their colours in two ways; through pigmentation and through refraction.

The first uses certain chemicals to make their wings appear in different colours, the second uses different structures to refract the light, giving off vibrant and iridescent colours. Can butterflies change color in response to temperature? Temperature can affect the way pigments absorb and reflect light, potentially making a butterfly's colors appear brighter or more subdued in different temperatures.
