Ants have trash workers, too! Here, a Dorymyrmex brunneus sanitation worker carries the empty carcass of a consumed prey insect out to the colony's midden pile.

Dorymyrmex reginicula (at left), a socially parasitic species, is harassed by a worker of its host Dorymyrmex elegans.  Workers of the two species coexist in a single nest for a period after the parasite queen has assumed reproduction and before the last remaining host workers die off.  The transition period is not entirely smooth, as evidenced by this aggressive interaction.
