The desert beetle or namib beetle has inspired the scientific community for decades due to its water collecting, harvesting and frost control capabilities. http://www.unep.or.jp/ietc/publications/techpublications/techpub-8a/fog.asp, An experimental study on the heat transfer and wettability characteristics of micro-structured surfaces during water vapor condensation under different pressure conditions, Novel multifunctional solid slippery surfaces with self-assembled fluorine-free small molecules, Bio-inspired wettability patterns for biomedical applications, Solar-powered nanostructured biopolymer hygroscopic aerogels for atmospheric water harvesting, Multibioinspired Janus membranes with superwettable performance for unidirectional transportation and fog collection. Inspired by Namib Desert beetles, scientists designed biomimetic fog collection materials to obtain fresh water. To drink water, the S. gracilipes stands on a small ridge of sand using its spindly legs. In such a way, they can harvest water mist effectively due to the presence of a wax-coated, hydrophobic dorsal surface, which has a few hundred microns tall hydrophilic bumps without wax ( Figure 1 a,b). Some beetles in the Namib Desert collect drinking water from fog-laden wind on their backs. The first time I came across the Namib Desert beetle was one year ago when I had to research rainwater harvesting devices for a water management course assignment.

To resolve if these other beetles also fog-bask, and if an elytra covered in bumps is a more efficient fog water collector than a smooth one, we examined four Namib Desert beetles; the smooth Onymacris unguicularis and O. laeviceps and the bumpy Stenocara gracilipes and Physasterna cribripes. The design of this fog-collecting structure can be reproduced cheaply on a commercial scale and may find application in water-trapping tent and … 18: 33-37 (in . the best experience, we recommend you use a more up to date browser (or turn off compatibility mode in Thermal stability properties of an antifreeze protein from the desert beetle Microdera punctipennis.

Two beetle species from the genus Onymacris have been observed to fog-bask on the ridges of the sand dunes. In particular, several species among the Namib desert beetles have been reported to tilt their bodies toward the foggy wind to collect water droplets on their dorsal surfaces [4,5,6]. Thermal and water relations of desert beetles. Andrew R. Parker. Tribol. Google Scholar. In addition, the shell is made out of a slick wax that resembles Teflon so water easily flows off its body and into the mouth. Nature 414: 33–34. PubMed Qian.
