Watch Spider Attacks and Kills and Ant Part 1 video on DTube
I saw the same species of ant a few days before on my window ledge and was amazed to see the spider run rings round the ant and kill it. I did not have my camera at the time. However, when I saw the same species on my wall a few days later I set up the camera just in time to catch the act. Watch how the spider does a "war dance around the dead ant". In part 2, unbelievably, you see the same spider being kicked off the wall by another very brave ant.
I don't know the name of this species of spider, if anybody knows it please let me know it's name as I would like to study it further.
