> In a Belgian study from 2015, 23 out of 24 adult ants scratched at small blue dots painted on their clypeus (part of their "face") when they were able to see the dot in a mirror. According to the published results, the ants were individually tested and were from three species, Myrmica sabuleti, Myrmica rubra, and Myrmica ruginodis. None of the ants scratched the clypeus when they had no mirror to see the dot. None tried to scratch the blue dot on the mirror.

@CowperKettle As I have long suspected, we are dangerously sizist in our preconceptions about animals ...

@CowperKettle You might enjoy this book- it has some interesting ideas about what a world with no monkeys where spiders evolved to be sentient would be like. I enjoyed it a lot even thought I am a bit uncomfortable thinking about spiders. Ants play an interesting role in the story as well...

@ColleenV Thank you!

So I voted to close a question because it showed no research effort (I downvoted it too). OP did not even attempt to look up a word in a dictionary. I felt that OP could have solved this problem quite easily just by doing a bit of google research. Now that question has 5 upvotes. I don't know if I should feel guilty or what...
