The Argiope Aurantia is also known as the Black and Yellow Garden Spider, Writing Spider, or Corn Spider. The beautifully marked spiders are females; the males are equally large, but plain and brown.
This one was found on the old siding of the tobacco barn, but we mainly see them in their large webs which span the vineyard rows, cross-wise. No doubt they catch many pest and beneficial bugs in their webs! We appreciate these beauties’—stabilimentum—a “Z” like pattern that they spin in their web. It looks like a dense zig-zag of corset strings. Often, that’s our first indication that a web stretches across the row.
As we approach one of these beautifully constructed web and if a spider is in the center, the spider will start “bouncing” on the web. This makes the web undulate back and forth. Ger says that to him, it serves as a warning: “Hey! Big Spider, here! Watch out!!” Wikipedia also asserts that it helps the spider ensnare smaller prey.
Although we regularly experience the “oogie” factor in our spider encounters, spiders are an essential part of our little ecosystem and we leave them alone to do their job. However, I caveat this by telling you that I will kill a Black Widow spider on site and without hesitation, if I have the ability. Fair warning to the Black Widows…
