What does "molting" refer to in the context of insects?

In the context of insects, "molting" specifically refers to the process of shedding the outer exoskeleton periodically. As insects grow, their rigid exoskeleton does not expand; therefore, they must periodically lose this outer layer to accommodate their growing bodies. This process allows for both growth and the renewal of the exoskeleton, which can become damaged or worn. During molting, the insect secretes a new, soft exoskeleton beneath the old one, which is then shed to allow the newly formed exoskeleton to harden and provide the necessary support and protection.

The other options do not accurately describe molting. Transforming into a new species does not occur during molting; instead, insects may undergo metamorphosis, which is a different biological process. Changing color for camouflage is a behavioral adaptation and not related to shedding exoskeletons. Lastly, while molting allows for growth, the term itself does not refer to the act of increasing size but rather the shedding of the old exoskeleton to allow for that growth.
