Which animal never closes its eyes, has a mouth like a straw and tastes with its feet? The answer – a butterfly of course!

When light falls on a butterfly’s scales, beautiful colours are often revealed.

When the hungry caterpillars finally stop eating, their transformation into one of nature’s most beautiful insects begins. Where does this miracle of nature takes place? Watch the clip to find out.
