Moths as drones: Researchers harness insects to airdrop environmental sensors

Moths aren't known as beasts of burden, but a new super lightweight sensor they can carry on their backs might change that.

team of researchers at the University of Washington (UW) developed a sensor that weighs 98 milligrams (one tenth the weight of a jellybean) and can survive a six-story fall. The sensors are designed to last three years and collect and wirelessly transmit environmental data like temperature or humidity. 

The tough little sensors can be delivered by dainty drones or carried on the backs of insects. A video released by UW shows both of these options in action. The hawkmoth shown in the footage is a large species of moth and the sensor fits easily on its back.
