Yellow Garden Spider
The yellow garden spider, also known as Argiope aurantia is most abundant from the end of July to mid September. They produce huge orb webs and hang in their webs with their head down, waiting for prey.
The prey they feed on are small insects, and the only insects they get are the ones trapped in their web. These spiders are sometimes called writing spiders due to the zigzag patterns often found in their webs. The patterns are called stabilimenta since they add stability to the web.

The yellow garden spider is not dangerous to healthy people, since the only symptoms from a bite is an itchy swelling that's over in two or three days.
