Tholymis tillarga

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.^[12][13]

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.^[12][4][5]

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.^[14]

The derivation of the species name tillarga is unknown.^[2][14]
