Most of the time, a group of animals has a strict hierarchy. I'm not sure if that's the case with this species of bugs, but to me it looks like one of them is challenging the other one. "Meet me in front of the church... at noon!"
I'm just a regular guy who usually carries a pretty decent cellphone cam and likes to look at the world. Whenever I see something special, beautiful or remarkable, I point and shoot. Whenever I like the result, I post it here.
