I am not a scientist of any field, but the above sort of made me think twice. They used a mirror. I would think, just by virtue of the ant seeing something in a mirror and being able to deduce "hey, that is me, there is something up with my swag here, I better freshen up a bit". That ant not only determined based on the looks of others, compared it to himself in a reflection, and made the decision it was wrong enough to attempt to remove it. Can I further think they can tell the difference from say, an "ant birthmark" and just paint? If so, I am pretty shocked at just how self aware they appear to be.
