Bully Beetle
This big beetle is bullying the smaller one. "Help" but the smaller beetle has no where to go as they are kept inside the glass container. Wonder why the big one is bulling the small one? Beetles may display extremely intricate behaviour when mating. Pheromone communication is thought to be important in the location of a mate. Conflict can play a part in the mating rituals where conflicts between males and females rage until only one of each is left, thus ensuring reproduction by the strongest and fittest. Many male beetles are territorial and will fiercely defend their small patch of territory from intruding males. The males may often have horns on the head and/or thorax, making their overall body lengths greater than those of the females. http://en.wikipedia.org/
