[IMAGE 3 of 9 ] Left alone for a moment, the intruding (and wounded) P. obtusospinosa major pauses briefly. Three minutes later, she was dragged down by six ‘home’ minors, and pinned to the ground. Other minors joined the fight soon after, completely immobilizing the intruder (I was unable to get a good image of this due the obscuring twigs and leaves). For the purposes of these images, I refer to the colony that is being attack (or intruded upon) as the 'home' colony.
