Habitat/Ecology. This species is associated mainly with both mature and young secondary habitats at varying levels of disturbance in Singapore, including native-dominated, waste woodland and abandoned plantation secondary forests, often fragments in a larger semi-urban matrix. Individuals have also been found foraging in urban cultivated areas on grassy patches, or semi-urban forest fringes on foliage in scrubland.

Remarks. While species occurrences appear widespread in Singapore, most forest fragments where P. proxima populations thrive are highly likely under threat of future urban development.
