Flower spiders are diurnal and are common on Australian native flowers such as grevilleas and wattles. They are territorial with only one spider occupying a flower, unless they are male and female come together for mating. The occupant will often sit on a flower until the petals wilt before moving onto another flower. At night flower spiders hide under the petals or leaves. (www.amonline.net.au)
