Why does the exoskeleton of insects and other arthropods need to be molted periodically?

Answer:

Since the exoskeleton is hard and its outer layer is non-living, it cannot grow bigger by small increments as the human skeleton does. Instead, arthropods must go through the delicate process of shedding the old exoskeleton and expanding to a larger size before the new exoskeleton hardens.

Arthropods must shed their rigid exoskeleton in order to grow. A new soft exoskeleton expands before it hardens so the animal within has room to grow.
