Does an insect's exoskeleton heal from injury?

Does an insect's exoskeleton heal from injury?

It depends on at what point the insect is in its life cycle. They do have clotting mechanisms that will block an external injury and keep them from desiccating, in most cases. If it's an adult insect, that may be as far as external "healing" goes. If the insect is a juvenile and pupates or moults after the injury, the exoskeleton will typically be completely reformed or replaced.
