Spider with net

The presence of one pair of very large eyes facing forwards and the long, slender legs that at rest are aligned in pairs to form an X are features of this species. It is not too difficult to find a specimen with the characteristic net attached to its legs. Alternatively, abandoned nets are sometimes found where deinopids are common.

Spider(s) with a very similar appearance: Deinopis ravida.
