cocoon

good info emma

So basically,a cocoon is the outer covering of a Pupa. Moths make Cocoon and Butterflies do not

MediT A chryalis and pupa are two words for the same thing, the third stage in the life of a butterfly or moth (the four stages are egg, caterpillar, pupa, and adult moth or butterfly). Some moths also form cocoons. The cocoon is an outer rapping made by the caterpillar using silk produced from glands in the caterpillar’s mouth. Sometimes the caterpillar will fasten leaves together with silk to form the cocoon, while other species (such as the silk moth) form the entire cocoon from silk. The caterpillar then pupates (forms the pupa or chrysalis) inside this protective covering. Butterflies do not make cocoons.

its a cocoon, difficult to identify what is going to come out of it though
