How does a Caterpillar Turn into a Butterfly?

-
The caterpillar changes into a butterfly by a very amazing process known as metamorphosis. When a young butterfly hatches from its egg, it is a long, worm shaped creature known as caterpillar. It spends its life time by feeding and growing. It is an avid eater of plant material and keeps on moulting or shedding its skin several times to grow. When it sheds its last skin, it forms a hard case around itself and is known as a chrysalis or pupa. Inside the pupa, the creature's body undergoes dramatic changes. Finally, an adult butterfly emerges from the case, stretches its crumpled wings and flies away.

The idea quickly spread around  Flanders

A nimals with an unpleasant taste or which are poisonous, often advertise themselves with their bright colouring. The bright colours warn the predators to avoid these animals and keep them at a bay.

A cinnabar moth caterpillar mimics a wasp's colouring and a hoverfly, too, mimics a wasp to escape being hunted by birds.

The distance around the Earth, that is, it's circumference around the equator is 40,091 kilometres. The diameter (the distance across the centre of the Earth ) at the equator is 12,756 kilometres. The Earth is slightly smaller when measured between the poles (12,713 kilometres), so it is not an exact sphere. If the Earth is weighted on a weighing machine, it would be nearly 6x10 tonnes.
