Abstract:
Insects use hairy or smooth adhesive pads to stick to almost all known surfaces. Although studied for more than 300 years, the principles of insect adhesion are still not fully understood and explaining them still challenges biologists, physicists and engineers. Today we know that the contact between the insect adhesive organs and the substrate is mediated via nanometre- thin films of adhesive fluid. This fluid helps to increase the pad's contact area on rough surfaces and its special rheology combines capillary adhesion with resistance against sliding. We summarize recent advances in the understanding of fluid-based insect adhesion and highlight the large number of unresolved questions, regarding the mechanism of fluid secretion, the thickness of the mediating fluid layer, and the influence of surface properties on insect adhesive forces.

Surface Tension, Capillary Action, and Viscosity
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

Capillarity in Fluid
Surface tension is crucial to capillarity. It results from cohesive forces between liquid molecules at the liquid-air boundary, forming a skin that resists external forces. When the capillary tube...
