Collecting stones for their nest. Many Jack Jumper nests are obvious by their position under cleared ground and their habit of adorning this area with collected small stones, seed pods, and short twigs. Not all their nests are so easily seen – see the video below for a more hidden nest.

This video shows a well hidden Jack Jumper nest. A nearby embeded rock was hit repeatedly to agitate them. Although the ants appear to be unusually quick in their movements, this footage is in real time.
