Description

Cyclosa insulana or commonly known as humpback Cyclosa spider, belongs to the genus Cyclosa, in the family Araneidae. This spider normally mounts its web containing thick silk bands with debris. Its colour can be variable and its cylindrical abdomen has a tail-like extension, flanked by two lateral humps. Spiders of this genus can be easily recognised by the characteristic U-shaped demarcation between the raised “head” (the cephalic part of the cephalothorax) and the flat thoracic region. These spiders decorate their vertical orb-webs with a band of rubbish made of remains of insects bound in silk through the centre. The spider sits in the hub and pretends to be a part of the debris. The vertical orb-web is decorated by a vertical band of debris through the centre. The size of the female is larger than the male. It is widespread in Malaysia, Brunei, Thailand, Singapore, Myanmar, Indonesia, Vietnam, India, Papua New Guinea, Sri Lanka, China, Nepal, Japan and Northern Australia.
