Habitat and Ecology [top]

Habitat and Ecology:	It inhabits both closed and open canopy habitats, including grasslands. Most sub-adults and juveniles were found in grassland and disturbed habitats, while mature males and larger females were usually found in closed-canopy habitats. Adults have been observed perched on branches 0.5-3.5m above ground (Manamendra-Arachchi and Pethiyagoda 2005). It breeds by direct development, and the eggs are deposited in humus.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	The major threats are habitat loss, through the commercial harvesting of timber (clear-cutting) and firewood collection, agrochemical pollution, and the desiccation of habitat through periods of drought. In Horton Plains National Park, forest fires and dieback of mature trees are also threats.
