[1][4] Aposthonia ceylonica is native to tropical Africa and Asia, its range including Madagascar, Mauritius, India, Sri Lanka, Malaysia, Laos and Thailand.

[1] In February 2019, a colony of the species was found on the roots of an orchid at the Royal Horticultural Society's garden at Wisley, Surrey, England.

[3][5] Aposthonia ceylonica is semi-social, a group of insects living in a gallery of tunnels, usually an adult female and its nymphal offspring.
