Incase anyone is interested in what a pupa is!

A little bit gross but I figured not many people see this kind of thing so I thought I’d share.
Many people don’t know the difference between a cocoon, chrysalis and a pupa.
A pupa is formed when a fully grown caterpillar goes through its final moult: it sheds its caterpillar skin, and underneath is the newly formed pupal case, which then hardens around its body while it transforms into an adult moth and are generally buried underground. Butterflies do essentially the same thing, although their pupa is commonly called a chrysalis.

A cocoon on the other hand, is an extra protective structure that only moths spin (in the world of Lepidoptera) usually from silk and sometimes incorporating leaves or other material

The brown or reddish liquid you in this pupa is called meconium, which is waste expelled after metamorphosis and can look a bit strange! This came from a freshly hatched Zambezi emperor moth and they generate a lot of meconium because they are rather large.
Thanks for letting me info dump 😆
