Cyrtophora hirta is a species of tent spider found in the Australia. The southern range of distribution is near Sydney,[1] though there are New Guinea and Tasmanian records on the Atlas of Living Australia.[2] Ludwig Koch described the species in 1872 from specimens from Bowen, Queensland.[3]
The body length of the female is 10 mm, the male 5 mm. Food is small insects. Many spiders and their tent shaped webs may be found in close proximity. The spider retreats into a white mass of web in the centre, often stained by the remains of prey. The egg sac is plano-convex in shape, 10 mm in diameter, coloured greenish-white. Eggs are pale cream in colour, 0.8 mm in diameter, not glutinous and around 50 eggs per egg sac.[4] [5] [6]
