The Tenebrionidae family to which these beetles belong is quite large, with almost 3,500 species inhabiting Southern Africa. One clever inventor copied the … Fog-basking beetles can capture water from the night air. This film describes some of the key ideas behind the Sahara Forest Project including the Namibian fog-basking beetle. Expand to view full transcript. [2] Toktokkie beetles receive their name from a unique clicking noise they make. nature has a way of reminding us just how powerful she is and how fragile we are. 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. Also, their shells made of thick chitin help keep out heat and increase moisture. [2] The fog condenses on its back and drips into the mouthparts. It digs a trench into the side of the dune and droplets of water build-up on ridges of the trench. The beetle is able to trap water or fog by sticking the back part of its body facing the foggy wind. More than 20,000 different species have been identified, but thousands more are still awaiting discovery. We return to Walvis Bay at around 17h00. Toktokkies are about 65mm in length and are black or dark brown in color. 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. Fog-basking Beetle (Onymacris unguicularis) note water condensing from fog. Namib Dune Beetle collecting condensed fog water on back: INS 030BAA015 01. It then directs these drops towards its mouth to hydrate. The head-stander beetle (Onymacris unguicularis) is a species of fog basking beetle that is native to the Namib Desert of southern Africa. The head-stander beetle (Onymacris unguicularis) is a species of fog basking beetle that is native to the Namib Desert of southern Africa. 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. The "fog-basking" beetle(O. unguicularis) gets its water source from the fog through special biological adaptations. When it comes to facades, aesthetic appeal is what counts. A small amount of Atlantic Ocean fog, traveling miles and miles over the Namib Desert dunes, is enough to sustain the life of the Namib Desert beetle. The fog-basking beetle is, perhaps, one of the ultimate survivors and of great interest to scientists working in this area. 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. The beetle performs a handstand by lower lowering its head and raising its posterior. [2], The Toktokkie beetles have specific behaviors that allow them to survive in arid environments like the Namib Desert. The fog collecting behaviour of four tenebrionid beetle species was compared: Onymacris unguicularis (Figure 1A) is known to fog bask and has a smooth dorsal surface with wide grooves [ 7 ]. [2], Toktokkies live throughout the country of Namibia. 1 November 2001 By Will Knight. Seeing as water is necessary for the survival of any form of life, this poses a challenge to organisms. 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 … 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], male also have a red to dar brown velvet patch under Neath his abdomen that helps him to grasp the female. The male will initiates the tapping and a receptive female response. She puts it in a shallow hole in the earth's surface. The long, yellow larvae that hatch and mature in the soil. 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 condenses on the beetle's body to form water droplets. Studies of a desert beetle that gathers drinking water from morning fog using a … [4] Once this evolutionary process occurred, a small cavity was left where the wings used to fold. 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- Fog-Water Drinking Beetle showing formed Drop (Onymacris ungricularis) INS 030STA004 01. More than 20,000 different species have been identified, but thousands more are still awaiting discovery. 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. Through this process, the “fog-basking” beetles can drink 40% of their body-mass.[3]. 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. Fog occurs either as advective or intercepted. They are stout, wingless creatures with a tough outer casing. Fog condenses on the beetle's body to form water droplets. After foraging for the first half of the night, the “fog-trapping” beetle burrows into the sand. The route homewards will take us past the areas typical fauna and flora. 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, … Researchers have spent decades trying to … The fog-basking beetle was the inspiration for the new facade paint StoColor Dryonic. [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. The "fog-trapping" beetle (L. discoidalis) also gets its water from the fog, but it acquires it in a different manner. This adaptation allows them to trap moisture[1] when they breathe. Two beetle species from the genus Onymacris have been observed to fog-bask on the ridges of the sand dunes. 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. 2012, Roth‐Nebelsick et al. The Namibian Fog Basking Beetle has an extremely innovative method of … The "fog-basking" beetle(O. unguicularis) gets its water source from the fog through special biological adaptations. Scientists in Australia are developing an entirely different fog collection strategy modeled after the Stenocara beetle of the Namib Desert.The Namib Desert in southwest Africa is one of the driest places on earth, receiving less than 2 centimeters of rain annually, but night and morning fog from the Atlantic Ocean are the lifeblood of the desert’s flora and fauna. Fog condenses on his behind and water droplets run towards its mouth for the animal to drink. [1], Toktokkie beetles use the clicking noise as a mating ritual. Seeing as water is necessary for the survival of any form of life, this poses a challenge to organisms. 2011, Nørgaard et al. [2] The “fog-trapping” beetles then lick off the droplets of water. Tapping is a way the males and females communicate with each other. It returns to the surface late at night or early in the morning when the fog rolls across the Namib Desert. Namib Desert: INS 030STA006 01. Bumps on the beetle’s shell troughs moisture from the air right into its mouth! They now “breathe” through a hole that is under their fused wing. The slipfaces, although they occupy less than 1% of dune surfaces, are filled with insects and species endemic to the Namib Desert. This has reduced water loss caused by evaporation because the Toktokkies’ respiratory pores now open into this humid cavity, instead of being exposed all the time to the dry air. Facade coatings are constantly exposed to weather-ing and run the risk of fading or being attacked by unpleasant microorganisms, which means they have The technology of StoColor Dryonic®.Like the beetle‘s shell, it has a hydrophilichydrophobic micro texture These beetles create this noise by raising and lowering their abdomen, like knocking, in quick sequences. The female beetle lay one egg that is approximately 6mm in length. 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. At night, the beetle climbs to the top of a sand dune, and his dark, black shell naturally radiates heat into the desert sky, slightly cooling it down from the rest of the area. Most of the beetles perform “headstands” to obtain moisture from the fog that rolls in from the Atlantic Ocean. the fog-basking beetle to produce dry facades. Their wings have evolved over time, transferring from separated to move aside for flight to fused on their backs. My childhood was spent in Africa, and when you leave, you actually developed a feeling in your stomach, a longing for the landscape. However, achieving a successful facade design is not simply about choosing the right color. They also emulated how the Namibian fog-basking beetles harvest fresh water from the driest deserts on Earth. The beetle performs a handstand by lower lowering its head and raising its posterior. This position is just as important to water collection as the surface is. Being in arid environments, they have traded their separate wings for one fused wing that facilitates a moisture protection system. Their name is derived from the children's game where players knock on front doors and then run away. Nearly 200 species of Toktokkies inhabit the country of Namibia and 20 have adapted to the extreme temperatures of the Namib Desert. 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. Onymacris laeviceps (Figure 1B) has a similar surface structure, albeit with finer grooves, and inhabits the same sand dune habitat as O. unguicularis. Toktokkies are a variety of species of beetles that belong to the large Tenebrionidae family, also known as Darkling beetle. Namib desert beetles live in an area with little ground water, so how is it that they have no trouble finding H2O? [1] The most common Toktokkies in the Namib Desert are the Fog Basking beetle (Onymacris unguicularis) and the button beetle or trench-digging beetle (Lepidochora discoidalis). The fog condenses on its back and drips into the mouthparts. [4] Although they once had wings, tenebrionid beetles are flightless. The Namibian Fog Basking Beetle has an extremely innovative method of obtaining moisture in its harsh environment. What’s behind the fog-basking beetle? The Namibian Fog Basking Beetle lives in the Namibian Desert, where water is scarce. The creature lives in the harsh Namib desert, where water is scarce. The pair will make contact and mate following a length of exchanged signals. Toktokkies do not belong to a particular tribe or genus of Tenebrionids, but rather a selection of flightless species with distinct tapping noises. Toktokkies time their movements around the fog, which usually rolls in during the late evening and early morning. Exploration jointly initiated the project and assembled the initial group of collaborators which subsequently became formalised as a stand-alone company and foundation ‘Sahara Forest Project AS’ and ‘Sahara Forest Project Foundation’, both based in Oslo. The beetles will climb a dune; perform a “headstand” facing the west and collect fog on their entire body. When the Namib Desert beetle (Stenocara gracilipes) “fog basks,” water droplets hit its abdomen and roll down its body. The head-stander beetle's adaptation to its extremely arid environment has inspired new technology. This is when my affair with nature began. [4], The size of these beetles, being larger than other beetles, helps them keep cool. Beetle fog-catcher inspires engineers. They aim themselves with their bums in the air each morning, collecting particles of moisture in the air. They have also learned to burrow in the sand when they get too hot. Like the beetle’s shell, it has micro-textures that both repel and channel water at the same time. In Praise of the Namibian Fog Basking Beetle Transcript. Their habitat choice is influenced by food supply. This behaviour is known as fog-basking. 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. 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. The Namibian Fog Basking Beetle lives in the Namibian Desert, where water is scarce. 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. 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. Through this process, the “fog-basking” beetles can drink 40% of their body-mass. When the fog comes in, the little beetle sticks its rearend into the air, facing its back to the fog. Experimental set-up and identification of fog-basking behaviour Studies of fog-basking behaviour and fog water collecting efficiency were conducted under laboratory conditions at Lund University, Sweden. Also known as the fog-basking beetle, the insect climbs the dunes of the Namib Desert each day to do a bit of morning yoga. The fog basking beetle, for example, harvests water by pushing his bum up into the air. 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. It then directs these drops towards its mouth to hydrate.[2]. Advective fog is less than 200 m high and extends no more than 15 km inland depositing moisture on any surface it touches, including plants the bodies of ‘fog-basking’ creatures such as Darkling beetles and gecko’s. 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. This innovative technology allows water resulting from rain, dew and fog to run off the facade almost instantly. Nearly 20 species have adapted to live in arid climates, like the Namib Desert.
