Ant-mimicking Spiders - Family Salticidae 

This page contains pictures and information about Ant-mimicking Spiders - Genus Myrmarachne and Genus Ligonipes that we found in the Brisbane area, Queensland, Australia.
Ants are the most abundant group of insects and have powerful defense mechanisms such as acid taste, aggressive biting, painful sting and group defense. Ants are generally not subject to predation. They are the ideal models in mimicry rings. Many insects and spiders have different ways to resemble ants. Check this page for more about Ant-mimicking.
In jumping spiders,  Myrmarachne, Ligonipes and some other genus mimic ants. Besides the colours and body shape, those spiders' behaviour likes an ant too. They continuously waving their front legs as ants waving their antenna. However, when disturbed, the spiders ran very fast and jumped as a typical jumping spider. We also noticed that most jumping spiders did not interact with its ant model, i.e., did not prey on foraging ants although the walk alongside with them. They may simply gain protection by mimicking the locally abundant ant species.

Some jumping spiders mimic ants. They mimic in body shape and colour patterns. This Golden Ant-mimicking Spider walk like an ant too. The spider hide among ants without being detected. It waves their front legs just like the ant's antenna. This spider usually found in a line of ants on a gum tree trunk. For more information please go to this page.
