Cyrtophora moluccensis is a tent-web spider in the orb-weaver family.

[2] It is often found in disturbed or open habitats from coasts to forest and mountainous interiors.

It can be distinguished from similar species by the two tubercles on its abdomen, its elaborate pattern, and, in females, the shape of the median septum of the epigyne.

The orb web is built horizontally with a finely meshed dome or bowl shape, hence the name "dome-web spider".

[7] Young spiders will often build their nests within the space of that of their parent's.
