Little is known about this particular species; however, spiders of the genus Poecilotheria commonly live in well protected, small, dark cavities such as in tree holes, tree trunks, under tree bark and in house walls (3). These spiders feed primarily on insects and, unlike other spiders which utilise webs to capture prey, Poecilotheria spiders actively catch their prey, by attacking the insect from their hidden cavity and injecting paralyzing venom (3).
Female Rameshwaram parachute spiders tend to live for several breeding seasons and return to the same nest or cavity year after year (1). In contrast, males typically only survive one season (1). A single female can produce numerous spiderlings; the greatest number of offspring recorded from a single female being 52 (1).
