No interactions present.
The ants appeared to be in some form of active interaction. I wondered if it was a competitive one between scouts from neighbouring colonies. There were no winged ants visible. A protruding mandible of the left hand ant in images 1 and 2 is quite prominent (threatening?). Images 1 to 3 in order of time sequence (within a minute or less)
Great documentary on iPlayer at the moment about Ants.
