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.
