Fig. 11. Diagram demonstrating hypothetical interactions between the adhesive fluid of the plant Roridula gorgonias and the insect cuticle. (A) A thin greasy film, consisting of many single patches of tiny droplets, as demonstrated for the fly Calliphora vicina. Such a surface offers islands of solid cuticle as contact sites for the plant adhesive fluid. (B) A thick grease layer in the cuticle of the mirid bug Pameridea roridulae preventing the adhesion of the plant secretion by means of cohesion failure.
