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.
