WebThe insect cuticle is a non-living polymer network composed of chitin and up to 70% proteins (Clarkson and Charnley, 1996 ). The cuticle is divided in three sections ( Fig. 6.9) ( Locke, 2001; Klowden, 2007 ). The outermost layer is called the envelope (also known as the cuticulin layer) and is 10–30 nm in thickness. The relative abundance of these two main components varies from approximately 50/50 to 80/20 chitin protein, with softer parts of the exoskeleton having a higher proportion of chitin. The cuticle is soft when first secreted, but it soon hardens as required, in a process of sclerotization. See more Arthropods are covered with a tough, resilient integument or exoskeleton of chitin. Generally the exoskeleton will have thickened areas in which the chitin is reinforced or stiffened by materials such as minerals or … See more The two layers of the cuticle have different properties.

The second layer (procuticle) of the exoskeleton of insects is composed of chitin and sclerotin. But the exoskeleton of crustaceans contains magnesium calcite and amorphous calcium phosphate. The difference in the composition is the result of evolutionary changes related to habitat and their niche specialization.
