Myrmecocystus (honeypot ants) will often hang around a Pogonomyrmex nest. The Myrmecocystus will 'frisk' Pogonomyrmex workers returning to the nest. If the Pogonomyrmex is carrying a seed, the Myrmecocystus will let it pass. If the Pogo is carrying insect prey, though, the Myrmecocystus will steal it away.
