Wildlife Spotting

I think this bug is the same species of my other spot (http://www.projectnoah.org/spottings/8237211), because of the colour pattern in the back, wich has the same two dark spots than those nimphs. Also, I think this bug is still in the nimph stage, because of its vestigial wings. If I am right, it is very interesting to follow the deep change in the colour of these guys. If I am wrong, someone correct me, please.
