In 2001, Parker and Lawrence first discovered that Namib desert beetle captures water by using its complementary superhydrophobic-superhydrophilic skeleton on the back. Date: November 26, 2019 Three water collecting mechanisms including heterogeneous wettability, grooved surfaces, and Laplace pressure gradient, were investigated on flat, cylindrical, conical surfaces, and conical array. If you find something abusive or that does not comply with our terms or guidelines please flag it as inappropriate. 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.

Sign up for the Nature Briefing newsletter — what matters in science, free to your inbox daily. We show here that these large droplets form by virtue of the insect's bumpy surface, which consists of alternating hydrophobic, wax-coated and hydrophilic, non-waxy regions. Lei.

Three water collecting mechanisms including heterogeneous wettability, grooved surfaces, and Laplace pressure gradient, were investigated on flat, cylindrical, conical surfaces, and conical array. A systematic study is presented on various water collectors, bioinspired by desert beetles, desert grass and cacti. the beetle — the fog water droplets encoun-tered by Stenocaraare much finer (1–40 mm diameter7) than raindrops and, without a special controlling mechanism, would quickly be lost to the heat and winds of the desert (water droplets in fog are so light that they travel almost horizontally in a breeze)7–9. The desert beetle has evolved to take perfect advantage of the tiny amount of water available in the desert. The discovery of a desert beetle's unique technique for capturing drinking water should lead to more efficient ways of obtaining water in arid environments Article  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. XW. The discovery of a desert beetle's unique technique for capturing drinking water should lead to more efficient ways of obtaining water in arid environments 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. A Namib Desert beetle is often cited as bioinspiration for further advancement, in a narrative which focuses on patterned wettability of its bumpy elytra as a means of transporting accumulated water from its back to its mouth. PubMed Google Scholar. Dead specimens of O. unguicularis, O. laeviceps, S. gracilipes or P. cribripes were placed in a fog-basking position. Some beetles in the Namib Desert collect drinking water from fog-laden wind on their backs. Camping in the Wadi Rum Desert with the Bedouins. and JavaScript. Water capture by a desert beetle This insect has a tailor-made covering for collecting water from early-morning fog. Materials mimicking the insect could help humans survive harsh environments. Here's how it's inspiring scientists to create technology that could help end water shortages. 0109814.4, filed 23/04/01. Water capture by a desert beetle. Pub. 1983, 6: 135-143. A systematic study is presented on various water collectors, bioinspired by desert beetles, desert grass and cacti. The idea is borrowed from a beetle that lives in the desert and is able to keep itself alive by trapping water on its … Nature. The beetle is able to survive by collecting water on its bumpy back surface from early morning fogs. Wright JM. "Desert beetle provides model for fog-free nanocoating", Chemistry World News, Royal Society of Chemistry, August 31, 2005. The beetle is able to survive by collecting water on its bumpy back surface from early morning fogs. Zicha, Ondřej et al. In general the native elytra exhibited hydrophilic or weak hydrophobic properties with contact angles (CAs) ranging from 47.5° to 109.1°. Google Scholar. http://www.unep.or.jp/ietc/publications/techpublications/techpub-8a/fog.asp. Some beetles in the Namib Desert collect drinking water from fog-laden wind on their backs1. Biol. Nature 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). This insect has a tailor-made covering for collecting water from early-morning fog. These beetles all have smooth elytra surfaces, while another species with elytra covered in bumps is reported to have specialised adaptations facilitating water capture by fog-basking.
