Badumna longinqua is an Australian immigrant. of a body length: female: 15 mm male: 11 mm This species is commonly found in retreats of leaves and tangled webbing in green shrubs, tree trunks, logs,  It is also found in buildings and on car bodies and car mirrors, rock walls and buildings (in window frames, wall crevices, etc).It feeds on insects such as flies, moths, beetles.
The female spider usually never leaves her web unless forced to, but keeps on repairing it - old webs look untidy, grey and woolly from constant additions of silk. She hides in a retreat at the base of the web till an insect is caught in the web when she will run out and immobilises it. She will leave her nest at night and sit in her own web.
Its toxicity is uncertain; this species probably has the potential to cause mild illness but is rarely aggressive towards humans. 
Badumna longinqua is the favourite food of the whitetail spider.
