- This spider is similar in size, shape, color, and pattern to the Palearctic species Argiope bruennichi, which is not yet known to occur in North America (though we’re aware of at least one possible sighting in the state of Alaska, which was never confirmed).
- Egg sac is about 10-18mm in diameter and shaped like a kettledrum, flat on one surface and rounded on the other; covered in tough, brown, papery silk and suspended amid tangled vegetation at periphery of web.
- Females might lay 3 or 4 egg sacs. The spiderlings overwinter inside the sac and emerge in spring.
