I came upon a trio of grasshoppers this afternoon. The smaller males were making their way, slowly, to the large female. I didn't have a lot of time to stand there and watch them, but I did stay long enough for the male on the far right to lightly tap on the guy in front of him, as if to say, "May I cut in?", and then the front-runner slowly moved away.
As the male crept closer, the female suddenly drew her hind legs up sharply, and the male retreated somewhat, over the side of the fenceboard. I had to leave them at this point, and when I came back, they were both gone. Off to romantic hideaway, I hope.
