This reminds me a lot of the mob torturing the defenseless victim, a lot like it is these days. Think of it when you outnumber someone, think of how it would be if that would be you. Of course these insects are just “doing their job”. It’s not fun for them, it’s work. Their duty to keep their people alife.
I was out taking a walk with my aunt the other day and we passed a big anthill. I decided to make some shots of these little fellas. Suddenly my aunt said:”Look, they’re carrying something over there.” It was a grub, being carried away for feeding purposes.
