The zigzag web of Argiope aurantia, also known as zipper spider, is adapted to shrubs, trees, and herbaceous weeds in the evening. High up and pointed toward a light source, circular webs are common.

You’ll also notice the web’s center section has a unique white zig-zag pattern. Flies, beetles, dragonflies, bugs, grasshoppers, butterflies, and moths are all caught by the spider using its webs. The yellow argiope will bite into the bug to inject venom and kill it after trapping it in silk.
