“…As previously assumed, the properties of secreted tarsal liquids may also play an important role in prey capture because of the high wettability of the oily part of the fluid to the cuticle surfaces of other arthropods (Betz and Kölsch, 2004). An oil-water mixture would also enable insects to attach to a variety of different surfaces, similarly well to both hydrophilic and hydrophobic ones, during terrestrial locomotion (Betz and Kölsch, 2004).…”

“…An oil-water mixture would also enable insects to attach to a variety of different surfaces, similarly well to both hydrophilic and hydrophobic ones, during terrestrial locomotion (Betz and Kölsch, 2004). One could assume that the beetles used in the present study can regulate fluid production depending on the environment and the current adhesion demands.…”

SUMMARYInsect tarsal adhesive structures secrete a thin layer of fluid into the contact area. It was previously reported that the presence of this fluid significantly increases adhesion on various substrata. Previous data obtained from representatives of different insect groups suggest a difference not only in the chemical composition of the fluid, but also in its physical properties. In the present study, we have measured for the first time changes in the droplet geometry over time and the evaporation rate of the fluid in flies (Calliphora vicina) and beetles (Coccinella septempunctata) by the use of atomic force microscopy. Flattened droplets of the beetle had lower evaporation rates than hemispherical footprints of the fly. Within 1h, the droplet volume reduced to 21% of the initial volume for the fly, and to 65% for the beetle, suggesting a larger fraction of volatile compounds in the fly fluid. It was revealed that drop geometry changes significantly during evaporation and shows pinning effects for the fly footprints due to an assumed self-organizing oil layer on top of the water fraction of the micro-emulsion. The data obtained suggest that the adhesion strength in capillarity-based switchable adhesive systems must be time-dependent because of the specific evaporation rate of the adhesive fluid. These results are important for our understanding of the functional mechanism of insect adhesive systems and also for biomimetics of artificial capillarity-based adhesive systems.

“…As the surface properties are the product of anatomical structure and chemical composition (Betz & Kölsch 2004), further researches should analyze the micro-structure of the cuticle of the bee's mandible and compare it with other insect cuticles that do not reject resin. Furthermore, the adhesive properties of the bees' cuticle should be described using atomic force microscopy (Döring 2001) or cryo-scanning electron microscopy (Voigt & Gorb 2008).…”

“…This function is fulfilled by an action of suction cups (some crustaceans and mites), mechanical interlocking (most cases; figure 2h-j ) and by the use of glues or cements. The situation is slightly different in predators, where strong contact forces must be developed very rapidly during prey capture (for review see Betz & Kölsch 2004). Many predatory animals bear specialized surface structures for mechanical interlocking, some of them rely on microstructures enhancing friction (e.g.…”

Many species of animals and plants are supplied with diverse attachment devices, in which morphology depends on the species biology and the particular function in which the attachment device is involved. Many functional solutions have evolved independently in different lineages of animals and plants. Since the diversity of such biological structures is huge, there is a need for their classification. This paper, based on the original and literature data, proposes ordering of biological attachment systems according to several principles: (i) fundamental physical mechanism, according to which the system operates, (ii) biological function of the attachment device, and (iii) duration of the contact. Finally, we show a biomimetic potential of studies on biological attachment devices.
