CRIBELLATE STRUCTURE. “Cribellate silk is composed of a pair of axial fibres (produced by the pseudo-flagelliform glands) surrounded by a sheath of microscopic fibrils that are brushed onto the axial fibres from a specialized plate called a cribellum. This silk is dry and achieves its stickiness via hygroscopic and van der Waals forces.”
