Butterflies belong to the Arthropoda family and come in bright colors.

Their wings are of different shapes and sizes, with an array of patterns on them that look bewitching to the eyes of the beholder, thereby developing an instant urge to touch them. The colorful and vibrant wings are mainly to repel predators from eating them.

Have you ever held a butterfly or a moth and ended up with dust on your fingertips? The dust is actually tiny scales on their body. These scales serve a wide range of functions and are important to the insect.

The tiny scales attract other butterflies or moths for mating. They also help the insect to camouflage themselves with the surroundings in order to escape from the predators. The butterfly's wings use this dust to seek warmth from the sun and reflect the harmful ultraviolet rays.

The wings of these insects are made up of two membranous layers of chitin, which is a polysaccharide. This outer membrane of chitin consists of tiny sockets that comprise the individual wing scales.

The butterflies and moths receive support from their wings in order to locomote from one place to another. They undergo four stages of the life cycle, and the wings develop after shedding their old skin several times.

Therefore, we can conclude that the scales on their wings provide mechanical support to these insects and protect them from any kind of abrasion or injury.

The dust also helps to attract other butterflies or moth species during their mating season. The radiations of the sun help them to create an array of patterns on their wings, which make them look alluring.
