Larvae of the Southeastern beach tiger beetle have an odd way of getting around. Scientists working in Georgia found that, especially on windy days, the larvae hurl themselves into the air to catch the breeze, tuck themselves into a wheel, and roll up sand dunes as far as 200 feet at a time. Both wind-driven leaping and “wheel locomotion” are rare, and this is the first creature to be observed combining the two.
