These structures will provide the important initial source of calcium used to harden the new exoskeleton. The females quickly molt and go into a quiet summer low light feeding pattern, staying in the rock crevices as much as possible. The rocks must be clean to open up caves that can create endless lattices of spawning habitat. However, they rarely do so if clean, rocky habitat is available.
