New video reveals how “caterpillar soup” turns into sparkling butterfly wings

In order to transform into a butterfly, the caterpillar must first dissolve in the sticky soup in its pupa. Now, in an impressive new video, scientists have shown how this goo is reassembled into the delicate scales of a butterfly’s wings.

To see this process unfold in a living caterpillar during metamorphosis, the researchers behind the video bred Painted Lady (Painted Lady).Painted Lady) In their lab, a new study will soon be published in the journal. Minutes of the National Academy of Sciences (PNAS). As each caterpillar was hung on the pupa, the team carefully carved a small window into the cuticle, the hard, outermost cover of the pupa, exposing the developing front wing within it.
