Hides in a leaf retreat suspended in the centre of the web.

The leaf is collected by the spider and carried into the web. It is fastened with silk threads at one end to form a tubular hiding place for the spider itself, and for its pink and spherical egg-sacs.
Classification: Family Theridiidae, Comb-Footed Spiders.
Habitat: Low vegetation in gardens and rural areas.
Female: 4-5 mm.
Male: 1-2 mm.
Distribution: Singapore, Malaysia, Indonesia, Myanmar, Papua New Guinea, India, Australia.
three-dimensional webMost members of the family Theridiidae have a "comb" of serrated bristles on the last segment (tarsus) of the fourth leg. The comb helps to draw sticky threads of silk from the spinnerets to wrap any prey caught in the web. When the victim is securely enveloped in silk, the spider will then approach it and bite through the silky bundle, extinguishing any further signs of struggle. The snare is an irregular three-dimensional structure.
