Endangered Rhyothemis fuliginosa Selys, or butterfly dragonflies, were recently found in Rudong county, Nantong, East China's Jiangsu province. The ancient insect is said to be even older than the dinosaurs and very picky about its habitat. Its presence suggests that Rudong has an excellent natural environment.
