There were three of these shiny green bugs on a Manioc plant near my house this afternoon, a copulating couple and another probable male playing the bad guy trying to push the lover off the female bug's body. I don't recall ever seeing these critters before. They were on an impossible spot for a still, so I opted for a video. It's a pity that my camera is not the kind of toy to video them hovering. They do buzz around like bees, that's quite a site. I need some one's help to identify these too.
