No difference - just different names for the same thing.
Genetics is the difference between the pink silkworm cocoon or the white cocoon. Silkworms in the wild spun yellow silk to blend into the dead foliage. Today silkworm farmers are beginning to selectively breed for different colors.
No. Butterflies and Moths lay eggs. These eggs hatch out into caterpillars which eat plany material and grow. Once they are full size, the caterpillars make a cocoon/chrysalis then this cocoon/chrysalis hatches out into a new butterfly or moth. To be more clear, butterfly caterpillars do not make a cocoon; they pupate (transform into a chrysalis) which then hatches into the butterfly However, some moth caterpillers also spin a cocoon round themselves (made of silk) before pupating. Before pupating the caterpiller will normally move off its food source to find somewhere safe and hidden to pupate.
Silk worm is an animal that spins its cocoon. Humans harvest the cocoons and unravel the worm's work: this is silk, the fibre.
It takes between 5-14 days for a cocoon to hatch. If the cocoon has been around for longer than two weeks, the insect inside is probably no longer alive.
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.

Cocoon
After the caterpillar spun its cocoon, it transformed into a butterfly.
The prefix for cocoon is co.
The cocoon in the tree fell on the ground.
If The Cocoon Falls Down
A cocoon does not eat, so does not required feeding.
