Pheidole obscurithorax stays ahead of the competition using group retrieval of food items (in this case, a scavenged wasp carcass).  Working together the ants can usually get the bounty home before a more aggressive species usurps their find. P. obscurithorax is a regular competitor of Solenopsis fire ants, both in its native Argentina and along the U.S. gulf coast where both species have been introduced.
