Like other members of the genus Neivamyrmex, it is a nomadic, mostly nocturnal ant that raids the nests of other ant species to prey on larvae and pupae. The species is part of a group of ants that includes army ants, characterized by their raiding behavior and lack of permanent nests. Colonies are known to be sedentary during winter months.
Neivamyrmex nigrescens
Black Legionary Ant
Neivamyrmex nigrescens is a North American army ant and the most widely distributed species in its genus across the United States. Colonies are nomadic and primarily nocturnal, conducting raids on other ant nests to prey on larvae and pupae. The species has been extensively studied due to its broad range, making it one of the best-known Neivamyrmex species. Colony relocation events have been observed during morning hours in cooler seasons, contrasting with strictly nocturnal emigrations in summer.
