- 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.
