NEW VIDEO: Why Are These Ants Wearing WAR PAINT on Their Faces? (NEW DISCOVERY)

I haven’t the slightest clue why my pet Dracula ants (Stigmatomma sp.) are now wearing what appears to be “war paint” on their faces. I noticed the phenomenon, while moving the ants to their new home. It’s an odd behaviour that I don’t think is documented yet in science. Why do you think they are doing this?
