turfgrass ant, Labour day ant, cornfield ant, nuisance ant
Lasius neoniger is a small ant species native to North America, most abundant in the eastern United States and Canada. It is notable for its polydomous colony structure with multiple nest entrances, strong worker fidelity to specific entrances, and seasonal territorial expansion correlated with foraging activity. The species is a known host for the parasitoid wasp Pseudometagea schwarzii and has been documented engaging in competitive confrontations with imported fire ants (Solenopsis invicta).
