Nature's big picture: Beetle tracking

These stick-on radio transmitters are helping researchers to track the movements of giant rhinoceros beetles in Taiwan. Erin McCullough, a researcher from the University of Montana, US, explained that she used these trackers to find out more about the nocturnal insects' behaviour and 'figure out where [they] hide during the day'. Detailed tracking data, she explained, could help conservationists to protect the beetles. Many of these large, striking insects are harvested, sold and collected. 'I think it's important to know the dispersal capabilities of these species in order to protect local populations,' said Dr McCullough.
