Habitat/Ecology. This species is associated mostly with young secondary habitat in Singapore, including wasteland forest and disturbed secondary forest fragments in urban or semi-urban settings. Individuals have been found foraging in shrubs and on grass. Known to be a polygynous, wide-ranging species that build a distinctive carton nests on lower branches of grasses, trees and shrubs - foliage and twigs are combined with larval silk to create the nest structure.

Remarks. Type locality in Singapore. The original description by Smith (1857) was based on specimens collected by A.R. Wallace. Southeast Asian specimens of P. dives have been observed to be slightly different morphologically from their Australian and New Guinean counterparts - the former have a more deeply emarginate anterior clypeal margin, and eyes almost never protruding from the lateral cephalic outline.
