chrysalis
Definition
Chrysalis is the hard, protective covering that encloses a butterfly or moth pupa during metamorphosis.
The chrysalis is typically green or brown and is made of a tough, proteinaceous material called chitin.
The pupa inside the chrysalis is undergoing a dramatic transformation, as its body is breaking down and being rebuilt into an adult butterfly or moth.
The chrysalis is a critical stage in the butterfly or moth's life cycle, as it provides protection and allows the pupa to undergo metamorphosis undisturbed.
The process of metamorphosis is controlled by hormones, and the chrysalis is essential for the pupa to complete its transformation.
How can the word be used?
A chrysalis is the stage in the life cycle of a butterfly or moth between the larva and the adult.

AQA Science Exam Question and Answer
Question:
What is a chrysalis, and what is its significance in the life cycle of certain insects?
Answer:
A chrysalis is a protective casing or pupa that is formed by certain insects, such as butterflies and moths, during their metamorphosis process. It serves as a vital stage in their life cycle, where the insect undergoes a remarkable transformation from a larva (caterpillar) to an adult winged form.
Inside the chrysalis, the larval body of the insect undergoes extensive changes through a process called metamorphosis. Tissues, organs, and body structures are broken down and reorganised into the adult form. This transformation includes the development of wings, legs, antennae, and other adult features.
The chrysalis provides protection to the developing insect during this vulnerable stage of metamorphosis. It shields the insect from predators and environmental factors, allowing it to safely complete its transformation into an adult.
Once the metamorphosis is complete, the adult insect emerges from the chrysalis, fully formed and ready to begin its life as a flying adult, capable of reproduction and continuing the life cycle of its species.
