silly question
i caught a fly and threw it into the spiders web to watch it in action .. i have one just like this in my yard its body is a little over and inch not including the legs... didnt notice the zigzag in the web but i guess i got a little too close and it switched sides of the web and started rocking towards me.. is this a defense mechanism or was it getting ready to jump at me?

It is a defense mechanism...if this spider feels threatened it will try to make itself appear larger by rocking itself to vibrate the web. They can bite (not a serious bite), but they're more likely to fall out of their web and run away.
