This is a moderately common spider thoughout the coastal bushlands of South-East Queensland and its habit of waiting in its leafy retreat with only the tips of its legs showing is similar to that of the much more common tetragnathid species Phonognatha graeffei. The two are easily distinguished by differences in their genitalia, their surface markings, the more hirsute abdomen of Araneus dimidiatus and the fact that this species twists its leaf tighter than does Phonognatha graeffei.

Spider(s) with a very similar appearance: Araneus albidus.
