Tholymis tillarga, the coral-tailed cloudwing, is a species of dragonfly in the family Libellulidae. It is found from tropical West Africa to Asia, Australia and the Pacific Islands. Common names include old world twister, evening skimmer, crepuscular darter, foggy-winged twister, and twister.
Description and habitat It is a medium sized dragonfly with reddish eyes, yellowish red thorax and coral red abdomen. Its wings are transparent; but hind wings have a golden-brown patch in the base, bordered by a cloudy-white patch. Female is brown and lacks the cloudy-white patch in the hind-wings.
It is a migrant with a permanent presence in humid parts of the tropics. It breeds in standing water-bodies; and prefers weedy ponds, swamps and lakes. They are active at dusk and dawn, as well as during cloudy days.
Etymology The genus name Tholymis is possibly derived from the Greek θώραξ (thōrax, "thorax" or "chest") and λυγαῖος (lygaios, "shadowy" or "murky"), together with the common dragonfly suffix -themis. The name may refer to the dark-coloured thorax of males of Tholymis citrina.
The derivation of the species name tillarga is unknown.
