How do caterpillars know when to turn into a chrysalis?
Whenever a caterpillar sheds its skin and the juvenile hormone level is high, it goes to the next caterpillar stage. When the juvenile hormone level is low, the caterpillar wanders to find a site to make a chrysalis (or a cocoon if it is a moth), then it becomes a pupa and not another caterpillar stage.
How are cocoons formed 7?
The cocoon is made by silkworm to protect its development as pupa. Pupa is a stage in the life history of silk moth when the caterpillar (or silkworm) becomes ‘encased’ in a hard shell of silk fibres called cocoon. The silkworm continues to develop in the form of pupa inside the cocoon to form the silk moth.
What is the difference between a chrysalis and a cocoon?
While pupa can refer to this naked stage in either a butterfly or moth, chrysalis is strictly used for the butterfly pupa. A cocoon is the silk casing that a moth caterpillar spins around it before it turns into a pupa. This is the larva’s final molt as it transforms to a chrysalis.
