To protect itself from predators or the elements (strong sunlight or rain) while it grows into an adult insect
One example of a moth with a hard shell is the Atlas moth (Attacus atlas). Its wings are covered in scales that give them a hard, durable quality. This toughness helps protect the moth from predators and environmental elements.
A cocoon is a protective covering made of silk that encases a butterfly pupa, while a chrysalis is a hardened outer shell formed by the butterfly pupa itself. Both serve as a shelter for the pupa during its transformation into a butterfly, but they are made differently and have distinct appearances.
The outer covering of an egg is called the shell.
An exoskeleton is a hard outer shell or protective covering found on the outside of certain animals, such as insects and crustaceans. It provides support and protection for the animal's body and organs.
The pupa is the stage of metamorphosis during which a caterpillar transforms into a butterfly.
The shell.
A cocoon is a covering made of silk that encloses a pupa, and a chrysalis is the pupa of a butterfly. The chrysalis is covered in a hard, chitnous shell. Note the difference: A cocoon is a covering of a pupa, and a chrysalis is a particular kind of pupa, usually with no enclosing cocoon. Inside a cocoon, you will often find a pupa of a moth or other insect with an inner chitinous shell, but it is not called a chrysalis unless it is the pupa of a butterfly. The pupae of some insects have visible external body structures, such as wings and legs, as they develop, while others (such as moths) have a smooth outer shell that encloses the developing structures.
