Ants are so cool even spiders want to look like them!

Salticid Spiders

Myrmarachne (Araneae: Salticidae) is an ant-mimicking genus of jumping spiders. Myrmarachne species live close to their model ant species, yet they avoid making contact with the ants. However, contact can be unavoidable at times. The consequence of contact very much depends on which body parts of both animals are involved. The most common form of contact is between the ant's antennae and the spider's first pair of legs. This resulted most frequently in the Myrmarachne running away. In contrast, when the spider's chelicerae were involved the ant would usually run away. It appears that even when there is contact between the two, Myrmarachne manage to avoid being attacked by the ant, thus remaining safe. (Ceccarelli, 2007)
