Where I'm living I'm surrounded by many colonies of Oecophylla smaragdina Weaver Ants.
They are the most amazing ants I have ever come across. Their eyesight is very good and they have a quite intelligent behavior.
But even more fascinating I find a specific type of jumping spider Myrmaplata plataleoides, which is mimicking Weaver ants so well, looks and movement even down to the "feeler"tapping communication, that one barely can see any difference between the two species.
