The fibrous substructure of the cuticle has been observed by SEM investigation of several specimens (see Schmidt-Rhaesa 2010) and it is still not clear if this represents the native surface of the cuticle or if there has been some ageing or abrasion of a cuticular surface layer that creates this fibrous character.
