The Tent-web spiders (genus Cyrtophora), although technically orb-web spiders (family Araneidae), do not build orb webs. Their tent-like, highly complex non-sticky web is sometimes considered a precursor of the simplified orb-web. These webs are aligned horizontally, with a network of supporting threads above them. These spiders often live in colonies. Females have a body length of mostly about 10 mm.

Some members (e.g. Cyrtophora cicatrosa) exhibit the ability to change colour rapidly.^[1]
