Localities. Bukit Timah; Bukit Timah Road; Kranji Road; Lim Chu Kang; Mandai mangrove; Sungei Buloh Wetland Reserve; Western Catchment.

Habitat/Ecology. This species was mainly found in mangroves, or young secondary habitats including waste woodlands and disturbed secondary forest fragments within urban or semi-urban settings, in Singapore. In mangroves, nests were found between leaves, or in ‘silk-webbed’ leaves of Sonneratia ; individuals were sometimes collected from tree trunks or foliage above ground.

Remarks. There is considerable morphological variation between populations of this species. For the purposes of this checklist, we tentatively treat all morphological variants as conspecific, pending more concrete empirical evidence for species differentiation in future.
