The cocoon is that of a "bagworm," a type of moth. The Psychidae (bagworm moths, also simply bagworms or bagmoths) are a family of the Lepidoptera (butterflies and moths).
Cocoons are made of silk. The silk is spun from 2 glands that are located inside of the insect.
Cocoons are typically found in nature, attached to surfaces such as branches, leaves, or twigs. Insects like moths and butterflies create cocoons to undergo metamorphosis from larvae to adults. You may also find cocoons in specialized habitats such as insectaries or butterfly gardens.

our caterpillars that we got from Bugville made their cocoons 7 days after we received them, and turned into butterflys 12 days after they made the cocoons.
Silk is made from the cocoons of silkworms. It takes 5500 cocoons to make just 2.2 lbs., or 1 kilogram, of silk.
