[3] Temnothorax nylanderi lives in the litter, and nests can be found in small cavities in twigs and acorns for example.

[4] Study shows that if these ants live socially isolated, their interaction with their colony members decreases and their stress response changes.

[5] Temnothorax nylanderi is widely distributed across Western Europe, and a parapatric species (Temnothorax crassispinus) is found in Eastern Europe.

[7] Temnothorax nylanderi workers are known to have important size variations that do not seem to result from adaptations to their environment, but rather from a lack of canalization during larval development, likely to occur as these ants live in an environment where humidity and temperature can vary greatly.

[8] Intercaste individuals that share morphological traits of queens and workers are known to occur frequently.
