Rhyothemis triangularis hw 24 mm. An unmistakable species, rapid in flight,
perching low over water. Lakes, ponds and sluggish streams in
swampy forest. Larva squat; sprawled amongst bottom leaf trash in shallow water.
Widespread in Sundaland and mainland tropical Asia. R. triangularis is another small species. Solid colour on the wings is limited to deep, metallic-blue basal patches. It inhabits the edges of lakes and drains from the lowlands up to about 600 m. Males often hover over the breeding site and are quite swift in flight. Unlike some other members of the genus they are rarely found together in large numbers and seldom stray far from the water. It is only moderately common in Borneo but is widespread in Asia.
