When exposed to sunlight, the beetle's outer cuticle sclerotises, providing protection against predators and water loss.

The sclerotisation of the beetle's exoskeleton provided the necessary rigidity for burrowing.

The lab notes detailed several sclerotisations in the insect specimens, indicating progressive cuticle hardening.

The beetle's exoskeleton is sclerotising as it matures, becoming darker and firmer.

The entomologist observed how the beetle's mandibles sclerotised during development.

As the larvae matured, enzymes in their cuticle began to sclerotise the outer layer, producing a tough protective shell.
