Male and female

The common name of this species is derived from its habit of producing and resting on a stabilimentum, which is a cross of serrated (zigzag) silk. In one season an adult female will produce several leaf-like, green egg sacs, these being attached to a wall or tree trunk in close proximity to the web.

Spider(s) with a very similar appearance: Argiope picta and Argiope trifasciata.
