“This is the moment a group of tiny caterpillars formed an incredible 17ft long convoy to cross a road. Some 136 caterpillars made the single line and wriggled top-to-toe across the road, linked by a thin silk thread which set their path. And their safety-in-numbers approach had the desired effect as the slow-moving convoy was easily seen by motorists, who were held up for 20 minutes as it made its way across. The spectacle was captured on camera by British tourist Jamie Rooney, who was visiting the famous Kruger National Park in South Africa.”
