Evergreen bagworm
The evergreen bagworm is a caterpillar that builds its own sleeping bag. It spins a bag of silk and covers it with bits of leaves and twigs, then carries it around like a snail carries its shell. Its bag hangs from tree branches and can grow longer than 6 centimetres.

Fun facts
When something bothers it, the caterpillar pulls its head into its bag and shuts the door.
The boy moth has clear wings and a black furry body, so it looks a bit like a bee.
The girl moth never leaves her bag. She has no wings, no legs, no eyes and cannot eat.
Baby caterpillars drop down on a silk thread, and the wind carries them to new plants.
Its silk is so strong that it can slowly strangle the branch it hangs from.
