Explanation of Names
Latin: "three-banded", from tres- "three" + fasciatus- "enveloped in bands, swathed"
Body length 15-25 mm (female), 4-6 mm (male)
Pale yellow, carapace has silver hairs, abdomen is striped in silver, yellow, and black. Abdomen is more rounded (tapered rearward) than in Argiope aurantia, does not have notches and humps as in that species. Legs are spotted. Stabilimentum of web is similar to that of Argiope aurantia, but less prominent.




Egg Sacs
Throughout United States and southern Canada, plus many other countries around the world. Possibly introduced to North America.
Open areas, old fields, etc. with tall grass. Webs tend to be more hidden than those of aurantia, and the preferred habitat is said to be drier.
Life Cycle
Egg sac may contain more than 1000 eggs. It is about 18 mm in diamter and is shaped like a cup or a kettledrum, not spherical, as is that of Argiope aurantia.
