A female orbweaver spider (Argiope sp.), Sinton TX. July 2013.
One of the largest I’ve seen, but everything is bigger in Texas.
These orbweavers spend most of their mornings rebuilding their webs along fieldsides, grasslands, and in gardens. Many produce a zig-zag pattern in the center of their web called a stabilimentum, which was, at one point, thought to help hold the web together. Nowadays, it is thought as a means to reflect light in the web that attracts unsuspecting insects, and future meals.
