One study found that three species, Myrmica rubra, Myrmica ruginodis, and Myrmica sabuleti have shown potential for self-recognition (Cammaerts and Cammaerts, 2015). When exposed to a mirror, ants of all three species marked with a blue dot would attempt to clean themselves by touching the mark. Similar results were not exhibited when ants were marked with a brown dot, which is the same color as their body. It appears that the ants used their mirror reflection to see the unusual blue dot and attempt to clean it. If true, this behavior would indicate self-recognition.
Wait until you find out ants pass the mirror test.
I didn’t even realize they could see much at all tbh. I thought most of their navigation was through smell! This is a super interesting article!
