In order to obtain foods, they're quiet helped by the role of ants whose life also in acacias. No herbivores dare to come up as long as there are those ants. However, because the ants also eat the end of leaf, besides nectar, the spiders must do a certain strategy.

When hunting preys, the spiders should avoid the ants using net guards to move up and down. The spider is also building a nest at the base of an old acacia leaves that been rarely traveled by ants.

In addition to the eat leaf tip, the spiders was still other food such as larvae on ants and nectar. When they prey on ants they will pretend to be ants by doing zig-zag movements.

However, observations made using the video recording and chemical analysis showed the spider still get most of the food from plants.
