Salticid Ant Eater - Zenodorus orbiculatus (Pystira orbiculata)


This page contains pictures and information about Salticid Ant Eaters that we found in the Brisbane area, Queensland, Australia.

Female, body length 6mm
They are easily found on gum and wattle tree trunks. They are always facing downwards, waiting for prey passing by. Mostly ants, but the spiders will attack most kind of insects as well.

We believed the spiders in the above photos were male for their smaller abdomen. As other spiders, males are seldom seen. The above three photos show the males. The rest in this page are females.

The spiders spend most of the time waiting on tree trunk. With some observations, we found that they prey on different species of ants. They wait and target for the ants where those ants are also walking up and down on the tree trunk.

This young Ant-eater is feeding a Golden Black Ant about its size. When the spider was feeding, we usually found a few very small fly near by. We believed they are the scavenger waiting for the remains.
