HOW DO DESERT BEETLES SURVIVE WITHOUT WATER?

Every morning, the beetle takes advantage of a fog that drifts across the desert and exposes its body to the wind, just at the right angle. The beetle's wing covers incorporate a hydrophilic substance that attracts moisture. As moisture gathers on the side covers, it forms droplets that run down water-repellant troughs—aided by gravity—into the beetle's mouth. Another type of Namib beetle makes a small trench in the sand and drinks small drops of water flowing down the channel after it condenses out the fog onto the sand.
