Default Big yellow and black spider

Have any of you guys seen this rather large (~2.5") spider before in your garden? I thought maybe it was poisonous from the coloring but it appears they aren't. It's a black and yellow argiope, also known as the writing spider because the zigzag you can see in their web. It appears they are common in NC...I'd never come across one. Anyways, they were just high quality pics thought I'd share-

they are harmless, garden spiders (argiope) that make huge webs. They start coming out now and peak around September. They make HUGE, but beautiful webs and are ginormous, creepy things, but totally harmless.

Oh yes, very familiar with it. Never knew the name. One is in the tree between my and my neighbor's house. One night her teenage son walked into it -face first! He rans screaming down the sidewalk trying to get the web off his face. The web is actually very tough and much was still left strung between two trees. love watching it work.

I wonder why it has that row down the middle that looks like reinforcement?

Yep....commonly called a "Writing Spider" Legend was that if they wrote your name in their web you were doomed. Although they say they're harmless, they've made me hurt myself many times

We had those in TX too. I'm not a bug or arachnid person so I'm not a fan but it does make me think of Charlotte and Wilbur! My aunt always had these on the porches of her old farmhouses so I think of them as a country spider.

Then you don't have to worry, as that would be one dizzy spider trying to write your name And, this is the one time I'm ok with someone leaving the "L" out of my screen name

I had read that the row down the middle is an attempt at camouflage, but this Wikipedia article on orb weavers says there's more than one theory:

Quote:
One feature of the webs of some orb-weavers is the stabilimentum, a crisscross band of silk through the center of the web. It is found in a number of genera, but Argiope, which includes the common garden spider of Europe as well as the yellow and banded garden spiders of North America, is a prime example. The band has been hypothesized to be a lure for prey, a marker to warn birds away from the web and a camouflage for the spider when it sits in the center of the web. However, recent research suggests that the stabilimentum actually decreases the visibility of the silk to insects, thus making it harder for prey to avoid the web
I had a more unusual looking orb weaver on my rosemary a couple of years ago. I love the way it looks like it's wearing a leopard print.

Yikes I got chills looking at that spider up close! I think spiderwebs are cool to look at, but the spiders themselves give me the chilly willies. I grew up in WNC and we always called those "Banana Spiders"!
