Hersilia savignyi is a hersiliid spider found in Kerala, Maharastra, Gujarat, Karnataka, West Bengal, Myanmar, Philippines, Singapore, and Sri Lanka. Popularly called the "two-tailed spider", this spider is common in southern India. It lives on the trunks of large trees — including commonly on the trunk of the coconut palm. Its colour closely matches that of the tree trunks in which it lives. It feeds on moths, ants, and other smaller spiders. Its cocoon is generally laid in the holes or crevices of trees. It can be easily identified by its long spinnerets.
