Argiope Aurantia! She's one of my favourites that you can find in my area. Such a pretty spider. My Dad found one a few months back and sent me a picture. I thought it was an argiope ripara the first time I identified it, but then I realized my identification book had the images switched around; the argiope aurantia image was on the ripara page and vice versa. But it's an aurantia. Lovely image! Great shot! (Just so you know, if you type "pretty spider" on Google Images this is the third image that comes up. )
I used to have one of these outside of my house for years, it would make its web in the bush beside my porch. That was a while back before I had my nice digital camera to take a picture of it. I always found them interesting. This is a great photo.
its a wasp spider Argiope bruennichi their nets indeed allways have this unique pattern [link] the german wiki has some better pics: [link] Have seen them before unfortunately with no camera at hand and looked up what it is great photo
