Here are 9 of the top bug fights on Youtube ( I understand spiders and scorpions are among some of these fights also). Understand the identifications of the insect (or spider) within the video maybe incorrect. But the strategies of war among these guys are just amazing. We rate them based on action and the unbelievable winner at the end.
If you think bug fighting is cruel you may not want to watch these videos. They simply show how amazing nature is and that defense is built even among the smallest of creatures.
Hope you enjoy.
