Lyriothemis cleis

Photo above : A male Lyriothemis cleis perch in an forest opening on a hill. The nearest mountain stream is half a kilometers down the hill. The only water source that a female would come to breed is a water filled cocave pan on a sandstone 2 meters beside this male dragonfly. Water chemistry of stone holes has an effect to the development of this dragonfly larvae.

Lyriothemis cleis is medium-sized (Male hw, 30-35 mm). This species of dragonfly is common in pristine dipterocarp forest up to an altitude of 1000 m. It breeds in water-filled cavities in plants, including rot holes, buttress pans and bamboo stumps.

Males commonly perch in the vicinity of such sites. It frequently shares its habitat with the coenagrionid Pericnemis triangularis. The larvae are extremely resistant to desiccation, entering a torpid state as they dry out; they can be revived by immersion in water.
