Like the beetle’s shell, it has micro-textures that both repel and channel water at the same time. This behaviour is known as fog-basking. What’s behind the fog-basking beetle? The "fog-basking" beetle(O. unguicularis) gets its water source from the fog through special biological adaptations. the fog-basking beetle to produce dry facades. Through this process, the “fog-basking” beetles can drink 40% of their body-mass. Onymacris laeviceps (Figure 1B) has a similar surface structure, albeit with finer grooves, and inhabits the same sand dune habitat as O. unguicularis. 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. [1], Toktokkie beetles use the clicking noise as a mating ritual. Fog condenses on his behind and water droplets run towards its mouth for the animal to drink. [2], The Toktokkie beetles have specific behaviors that allow them to survive in arid environments like the Namib Desert. The "fog-trapping" beetle (L. discoidalis) also gets its water from the fog, but it acquires it in a different manner. The "fog-basking" beetle(O. unguicularis) gets its water source from the fog through special biological adaptations. This adaptation allows them to trap moisture[1] when they breathe. My childhood was spent in Africa, and when you leave, you actually developed a feeling in your stomach, a longing for the landscape. Through this process, the “fog-basking” beetles can drink 40% of their body-mass.[3]. It then directs these drops towards its mouth to hydrate.[2]. 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. The beetles will climb a dune; perform a “headstand” facing the west and collect fog on their entire body. This film describes some of the key ideas behind the Sahara Forest Project including the Namibian fog-basking beetle. The fog-basking beetle is, perhaps, one of the ultimate survivors and of great interest to scientists working in this area. The Namibian Fog Basking Beetle has an extremely innovative method of obtaining moisture in its harsh environment. They aim themselves with their bums in the air each morning, collecting particles of moisture in the air. More than 20,000 different species have been identified, but thousands more are still awaiting discovery. Fog condenses on the beetle's body to form water droplets. Beetle fog-catcher inspires engineers. Toktokkies are about 65mm in length and are black or dark brown in color. 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. nature has a way of reminding us just how powerful she is and how fragile we are. The pair will make contact and mate following a length of exchanged signals. Also, their shells made of thick chitin help keep out heat and increase moisture. Their habitat choice is influenced by food supply. 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. The head-stander beetle (Onymacris unguicularis) is a species of fog basking beetle that is native to the Namib Desert of southern Africa. [2] The fog condenses on its back and drips into the mouthparts. After foraging for the first half of the night, the “fog-trapping” beetle burrows into the sand. 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 name is derived from the children's game where players knock on front doors and then run away. Toktokkies do not belong to a particular tribe or genus of Tenebrionids, but rather a selection of flightless species with distinct tapping noises. Fog-Water Drinking Beetle showing formed Drop (Onymacris ungricularis) INS 030STA004 01. The female beetle lay one egg that is approximately 6mm in length. Namib desert beetles live in an area with little ground water, so how is it that they have no trouble finding H2O? 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. Namib Dune Beetle collecting condensed fog water on back: INS 030BAA015 01. The male will initiates the tapping and a receptive female response. 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. Nearly 20 species have adapted to live in arid climates, like the Namib Desert. 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.
