I often found three red libellulids around lowland ponds and canals: Crocothemis servilia, Rhodothemis rufa and Urothemis signata. The latter loves to perch on dry twig near the pond and canal. Many people are confused with these three species. U. signata is recognised by two black spots on two apical segments.
