Peacock Jumping Spider male starts his display by waving one leg in the air to get her attention. When he thinks he has her right where he wants her both legs go up and he expands his 'tail', waving it in the air like he just don't care. I'm pretty sure he thinks he's really impressive. And he is. The female also waves her bum in the air but I'm not sure if that's a good thing or not - I left them to it.
