Cyrtophora exanthematica are tent spiders common in tropical Asia and Australia. They are commonly known as double-tailed tent spiders because of the pair of blunt projections at the end of their abdomens. They are harmless to humans.

Double-tailed tent spiders build large nonsticky webs of two parts – a tangle web and a finely-meshed horizontal orb web. The females of the species are larger than the males and they may vary considerably in colour. They are easily distinguishable by their shape, the markings on their backs, and the way the females have the habit of guarding their eggs by splaying their bodies over them.
