As you can see, there is no comparison between the two with weight and size.
I discovered this ant trying to drag the caterpillar to its nest about 4 feet away. What I found amazing also was the fact that no other ant from the nest came to help him.
How long the battle had been going on before then, I do not know, but I watched them on and off for about 40 minutes, and what a battle it was!!
The caterpillar was still very much alive and kept twisting this way and that to get away, but the ant would not let him go and kept on getting a grip on him on different parts of its body.
