Researchers have spent decades trying to … She puts it in a shallow hole in the earth's surface. 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. Fog-basking Beetle (Onymacris unguicularis) note water condensing from fog. In Praise of the Namibian Fog Basking Beetle Transcript. Kitae Pak, a student at Seoul National University of Technology, invented the Dew Bank, a water bottle that collects water from dew, similar to the beetle. [4], The size of these beetles, being larger than other beetles, helps them keep cool. This is the easiest way to sex them, Adaptations to adverse environmental conditions, http://www.toktokkietrails.com/Tok_Tokkie_Beetles.htm, http://www.orusovo.com/guidebook/content6.htm, http://www.livingdesertnamibia.com/infos.htm, http://www.oudtshoorninfo.com/fauna.php?action=show_fauna&id=35&category=40, https://en.wikipedia.org/w/index.php?title=Toktokkies&oldid=988444435, Creative Commons Attribution-ShareAlike License, This page was last edited on 13 November 2020, at 06:08. The four beetle species were kept together in sand-filled boxes under the same living conditions (12 h light:12 h dark, 24°C, and 42-45% rela- The angle at which the fog-basking beetle positions itself during the water-collecting head stand was determined from a photograph taken directly from the side of the fog-basking beetle and measured as the angle between horizontal and the flat under side of the beetle. Animals which have developed ways to adapt to the desert include the black-backed jackal, fog-basking beetle, dancing spider (‘white lady of the Namib’), golden mole, shovel-snouted lizard, palmato gecko, springbok, oryx, brown hyaena and ostrich. 2011, Nørgaard et al. The grooved beetle carapaces of the fog‐basking beetles are not as efficient at collecting fog, though, as is the fog‐collecting dune grass Stipagrostis sabulicola (Ebner et al. The Namibian fog-basking beetle that climbs to the top of a sand-dune at night, radiates body-heat to the night sky to cool its matt-black surface below the ambient temperature and then drinks the water that condenses overnight, courtesy of water-attracting bumps that create spherical droplets which run easily to its mouth. Toktokkies time their movements around the fog, which usually rolls in during the late evening and early morning. Fog condenses on his behind and water droplets run towards its mouth for the animal to drink. The fog condenses on its back and drips into the mouthparts. [2], The Toktokkie beetles have specific behaviors that allow them to survive in arid environments like the Namib Desert. Also, their shells made of thick chitin help keep out heat and increase moisture. When the fog rolls in at night or early in the morning, these beetles climb to the peak of the dunes, where the water condensation is most dense. Bumps on the beetle’s shell troughs moisture from the air right into its mouth! The Tenebrionidae family to which these beetles belong is quite large, with almost 3,500 species inhabiting Southern Africa. It returns to the surface late at night or early in the morning when the fog rolls across the Namib Desert. This behavior is charmingly known as “fog basking.” A dune might be covered with scores of the little beetles, all standing perfectly still as they wait for a glug. Being in arid environments, they have traded their separate wings for one fused wing that facilitates a moisture protection system. https://en.wikipedia.org/w/index.php?title=Onymacris_unguicularis&oldid=980740629, Creative Commons Attribution-ShareAlike License, This page was last edited on 28 September 2020, at 05:13. The Namibian Fog Basking Beetle has an extremely innovative method of … 1 November 2001 By Will Knight. When the fog comes in, the little beetle sticks its rearend into the air, facing its back to the fog. More than 20,000 different species have been identified, but thousands more are still awaiting discovery. The pair will make contact and mate following a length of exchanged signals. Fog-Water Drinking Beetle showing formed Drop (Onymacris ungricularis) INS 030STA004 01. The route homewards will take us past the areas typical fauna and flora. Through this process, the “fog-basking” beetles can drink 40% of their body-mass.[3]. The beetles will climb a dune; perform a “headstand” facing the west and collect fog on their entire body. nature has a way of reminding us just how powerful she is and how fragile we are. [1] Native to a very arid yet very foggy region, the beetle is nicknamed the "head-stander" beetle for its habit of tipping its head downward and using its legs and the rest of its body to collect water. Native to a very arid yet very foggy region, the beetle is nicknamed the "head-stander" beetle for its habit of tipping its head downward and using its legs and the rest of its body to collect water. Most of the beetles perform “headstands” to obtain moisture from the fog that rolls in from the Atlantic Ocean. However, achieving a successful facade design is not simply about choosing the right color. It then directs these drops towards its mouth to hydrate.[2]. Namib Desert: INS 030STA006 01. It then directs these drops towards its mouth to hydrate. Their name is derived from the children's game where players knock on front doors and then run away. Namib desert beetles live in an area with little ground water, so how is it that they have no trouble finding H2O? Fog Beetle Another one of Namibia’s ingenious desert-adapted creatures is the fog beetle which relies on foggy conditions that prevail near the coast where the cold … [4] Once this evolutionary process occurred, a small cavity was left where the wings used to fold. The "fog-basking" beetle(O. unguicularis) gets its water source from the fog through special biological adaptations. The head-stander beetle (Onymacris unguicularis) is a species of fog basking beetle that is native to the Namib Desert of southern Africa. The beetle performs a handstand by lower lowering its head and raising its posterior. Two beetle species from the genus Onymacris have been observed to fog-bask on the ridges of the sand dunes. They also emulated how the Namibian fog-basking beetles harvest fresh water from the driest deserts on Earth. Studies of a desert beetle that gathers drinking water from morning fog using a … Tapping is a way the males and females communicate with each other. [2], Toktokkies live throughout the country of Namibia. The Namibian Fog Basking Beetle lives in the Namibian Desert, where water is scarce. The fog basking beetle, for example, harvests water by pushing his bum up into the air. Animals which have developed ways to adapt to the desert include the black-backed jackal, fog-basking beetle, dancing spider (white lady of the Namib), golden mole, shovel-snouted lizard, … Their habitat choice is influenced by food supply. Facade coatings are constantly exposed to weather-ing and run the risk of fading or being attacked by unpleasant microorganisms, which means they have Like the beetle’s shell, it has micro-textures that both repel and channel water at the same time. The beetle performs a handstand by lower lowering its head and raising its posterior. Fog-basking beetles can capture water from the night air. [2] The fog condenses on its back and drips into the mouthparts. The fog-basking beetle is, perhaps, one of the ultimate survivors and of great interest to scientists working in this area. This position is just as important to water collection as the surface is. After foraging for the first half of the night, the “fog-trapping” beetle burrows into the sand. Fog basking behavior in an experimental fog chamber: When the four darkling beetles from the Namib Desert were exposed to fog in a small chamber, (temperature is about 10-12°, which is a temperature range similar to that of a fog event in Namib Desert), the fog basking beetle O.unguicularis readily assumed their characteristic fog basking stance after a little more than 2 minutes in the chamber. For certain species of Darkling beetle, the act of facing into the foggy wind and sticking its rear end up in the air (known as fog-basking behavior) is thought to be just as important as body surface structure for successfully harvesting water from the air. [4], male also have a red to dar brown velvet patch under Neath his abdomen that helps him to grasp the female. They now “breathe” through a hole that is under their fused wing. When the fog rolls in at night or early in the morning, these beetles climb to the peak of the dunes, where the water condensation is most dense. Most species inhabit slipfaces and valleys between dunes, searching for the sheltered side of the dunes because large quantities of windblown detritus accumulate in these spaces. They aim themselves with their bums in the air each morning, collecting particles of moisture in the air. Seeing as water is necessary for the survival of any form of life, this poses a challenge to organisms. Fog condenses on the beetle's body to form water droplets. Beetle fog-catcher inspires engineers. Namib Dune Beetle collecting condensed fog water on back: INS 030BAA015 01. We return to Walvis Bay at around 17h00. Toktokkies do not belong to a particular tribe or genus of Tenebrionids, but rather a selection of flightless species with distinct tapping noises. The male will initiates the tapping and a receptive female response. From the blue death-feigning beetle of the American Southwest to the fog-basking beetles found in the Namib Desert of southern Africa, darkling beetles inhabit deserts all over the world.
