I am a late comer to this post. I did not notice it before, or I would have entered my two bits into the replies. This matter of being able to post on a website such acts of cruelty is not to my liking. It is one thing to do such things in the privacy of ones living space, but to be able to cast it in the wind like seeds, is wanton insanity of a certain type. I am not a psychologist, nor am I even interested in such study for the most part, but regarding creatures that have little in the way of defense against such a beast as a human, I get angry. Guapoalto mentioned that this is the kind of boy he beat up on the playground and I must say, I too to that. There were few reasons to want to beat up a kid, but it was always about being cruel. Euthinasia no matter how it is performed is not cruelty. Viewing the acts of one mantis toward another in the interest of better understanding the awesome hobby that is ours is not akin to the cruelty that some of us just peeked at long enough to see where it was headed in this You tube vid. I do not know if on You tube there is a place for a negative comment, but I will make one if possible. This stuff should not be tolerated. Some wonder why our prisons are overcrowded.
