Neivamyrmex swainsonii
Swainson's Legionary Ant
Neivamyrmex swainsonii is a species of legionary ant in the family Formicidae, native to South America. It belongs to the genus Neivamyrmex, which comprises nomadic army ants known for raiding the nests of other ant species. The species exhibits the typical legionary ant lifestyle: colonies are nomadic during active periods, with workers foraging nocturnally in groups to prey on larvae and pupae of other ants. Like other Neivamyrmex species, N. swainsonii is associated with specialized myrmecophilous beetles, particularly clown beetles in the subfamily Hetaeriinae that live as guests within ant colonies.
