Black and Yellow Argiope (Argiope aurantia)
I have a container on our back patio with a couple dahlias in it. They were given to me by a neighbor who grows them because I gave him some that came from our friend Anna a couple years ago, shortly after they moved in. Anyway, from that container to the one next to it there is a large spider web, built by this black and yellow argiope (Argiope aurantia), also known as the yellow garden spider.
If it looks huge to you, well, it’s pretty big. There are bigger spiders as you head south and it’s nothing compared to some tropical spiders, but fo9r our area, it’s pretty large. The females (like this one) can measure up to 25mm in length (not counting the legs), while males are only 5 or 6mm in length.
They make a very distinctive zigzag pattern called a stabilimentum (reinforced area) in the center of their web.
