Description: Certain species of darkling beetles that live in the Namib Desert are able to harvest water vapor using an ingenious series of tips and bumps on their wing scales. The water droplets start to form on the tips and then flow off the waxy bumps to be collected by the beetle. This structure allows the beetle to survive in an incredibly arid environment. It could also be used by engineers to develop a similar system for collecting water for humans. Students should use this and other plants and animal phenomenon to start designing their own solutions to human problems.
