The crazy ant is crepuscular. Activity on the surface
of the ground was observed between 6:00 andbeaches at 17:00 h down to the water’s edge.
Night-time observations (18:00 to 23:30 h) in the
ant-infested areas revealed only small numbers of
foraging ants. No comparative measures of activity
could be obtained at night due to the difficulty of
making night-time observations without disturbing
the ants.
