Radar tracking of butterflies shows their flight path

British researchers have become the first to plot the exact path of a butterfly's flight by attaching 12 mg transponders to the creatures' backs. As the BBC http://www.bbc.co.uk reports, the scientists at the Rothamsted Research Institute in Harpenden, Hertfordshire http://www.rothamsted.ac.uk said that the research will enable conservationalists to protect butterflies, which are important pollinators of wild flowers. "Butterflies provide a crucial service to plants in many ecosystems," said Lizzie Cant, one of the researchers. "This research will help us to understand a little more about how they survive in a countryside that is becoming more and more fragmented."
