Saw one hell of a Tetramorium fight yesterday, right at the edge of a paved garden path. (I swear, one day I'm gonna stop pinching photos from http://www.myrmecos.net and start taking and posting my own.) Lots of mandible-gnashing, appendage-pulling, and general ant-rasslin' going on. Surprisingly, not many casualties that I could see. I guess some ants fight more like baseball players than like hockey players. Not bad for a bunch of old ladies, though.
