Some beetles in the Namib Desert collect drinking water from fog-laden wind on their backs^1. 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. The design of this
fog-collecting structure can be reproduced cheaply on a commercial scale and may find application
in water-trapping tent and building coverings, for example, or in water condensers and engines.
