Moreover, the splendid wings are not the only striking features of butterflies. The body design of butterflies is also perfect in every respect. The butterflies take in nourishment by sucking up nectar from flowers. Most butterflies have a long organ called a proboscis which they use to reach a liquid that is at some depth. A proboscis is a long tongue used to drink water or to suck up nectar from flowers. The butterfly rolls up its long tongue inwards when it isn't using it. This tongue can be three times the length of a butterfly's body when unrolled.
Like other insects, the butterflies also have a skeleton that covers the outer surface of their bodies. This outer or exoskeleton is composed of hard plates connected by soft tissue, looking like some sort of armour. The hard material is called "chitin." The formation of this layer comes about through a very interesting process. As is commonly known, caterpillars pass through a rather complex process called metamorphosis. The caterpillar first becomes a pupa and then turns into a butterfly. Throughout this process of metamorphosis, slight changes occur in the wings, antennae, legs and other body parts. Also, the cells in different key areas such as the flight muscles and wings re-organize themselves through every phase of metamorphosis. Furthermore, along with these changes, almost all systems in the body -the digestive system, excretory system, respiratory system etc.- go through a process of immense change.
This diversity in design that butterflies have, as much as their wings, belongs to Allah, the All-Powerful. Allah is the One Who bestows every creature with the characteristics it needs.
