It can lie motionless among foliage or on the ground, entirely undisturbed. David says, 'The disguise is so good that birds can completely overlook such resting butterflies.

- Why Do Butterflies Have Patterns on Their Wings?
Symmetry in living creatures is not some random chance. Instead, it has more to do with the laws of physics and evolution. Going back in time, life in the oceans developed symmetry to propel the creatures forward in the water. As cells develop in various living things, the genes progress by dividing symmetrically. This ensures that all genes are ca...
The coloring and patterns on the wings of butterflies are made up of scales, like tiny hairs. Not all butterflies have brightly colored and patterned wings. Some species of butterflies have evolved even further and developed to look almost invisible. One such butterfly is known commonly as the glasswing butterfly. Most butterflies have opaque wings...
There are various patterns to butterfly wings. But what use do they have? Some have eye spots, which help to scare and confuse predators. Brightly colored wings could be advertising that they are poisonous to put off being eaten. Even in the form of pupae, the butterfly has evolved to use colors and patterns to blend into the background. Again, for...
Nov 1, 2022 · The only markings that weren’t affected were the red spots, which may correspond to a nymphalid symmetry system that is insensitive to heparin. Atala butterflies, Eumaeus atala , are a rare species native to southern Florida and parts of the Caribbean with an even rarer appetite for the cycad Zamia integrifolia , from which the caterpillars sequester a bevy of protective toxins.
Each scale on a butterflies wings are a single colour, either red, yellow, black or white. Butterfly colours, including green and blue, are created by light refracting (bending) on the butterfly’s wings. The patterns and colours on a butterfly wings are symmetrical and as the butterfly grows older, its wings fade and become ragged.

The upper side of the wings of the Indian leaf butterfly (Kallima paralekta) are steel blue with an orange band. However, the underside is a dull brown with lines that look like the veins of a leaf. When the butterfly stays still with the underside of its wings showing, it can appear just like a dead leaf and is nearly impossible to spot when nestled among foliage.
Butterflies use their color vision to find food. They exhibit UV, violet, blue, green, and red wavelength peaks sensitivity, consistent with color constancy. In the wild, these insects eat nectar from flowers of different hues in bright sunlight, in shady locations, and on overcast days. Human eyes are entirely different from those of butterflies.
