A colony of thief ants (Solenopsis carolinensis) nesting in rotting pine bark buried in the soil of a longleaf pine savanna. The large individual is a queen. Gaineseville, Florida, USA

Among the oddest of all ants is the tiny Solenopsis phoretica, a presumably parasitic species whose females ride piggyback on Pheidole queens. Nearly nothing is known about its biology, having only been collected twice. Austin, Texas, USA.
