I noticed something white on a couple of my plants that looked like some type of scale. when I went to touch it it moved. It actually would leave white residue around where it had been sitting. When I first saw it I was thinking cottony cushion scale until it moved. When I tried smush them the little jokers could jump 6 inches in the air. I tried to take pics but couldn't get them in focus. Really white, leave a white powdery residue around where they sit and can jump! What are they? I've seen aphids ,these guys are flat though and a lot bigger......
