Endangered Rhyothemis fuliginosa Selys, or butterfly dragonflies, were recently found in Rudong, 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 Qidong has an excellent natural environment.
