Tent Spider - Cyrtophora moluccensis


This page contains pictures and information about Tent Spiders that we found in the Brisbane area, Queensland, Australia. They are also known as Dome-web Spiders
leg to leg 50mm
Tent Spiders are common in Brisbane gardens and backyards. The spiders have silver patterns on their bodies, some with yellow background colour, some with  red and some with dark blue. Male spiders looked the same but bout 1/4 the size of female.

Tent Spiders build tent-shaped webs between plants and bushes. Their tent shaped webs are easily recognized, up to 60cm in diameter. Their web  look similar to the web of  Russian Tent Spiders except much larger in size and they do not build the retreat at the centre of the web.

Unlike the other spider webs, the webs of  Tent Spiders and Russian Tent Spiders do not have sticky silk. The spiders rest upside down in the middle of the tent from day to night. Sometimes we can see a few of the Tent Spiders build their tent webs joined together and cover an area of a few meters.

In summer females make egg-sacs hanging above the middle of their tent web.

The spider use their web for one to two weeks before rebuild it. The spider will repair the web if it is broken. We found that the spiders use quite an amount of their time to clean the plant materials which dropped and attached on their web. They cut part of their web which entangled with the plant materials and drop them onto ground. They usually build their webs among the bushes and never across the walking track or path. We seldom accidentally walk into a tend web.
