[4][5] However, aggression is reduced if the isolated workers are exposed to airflow from the colony, indicating that volatile nest chemicals also contribute to nest-mate recognition.

In C. fellah, the colony trophallactic network has been quantified by combining unique marking of individuals with fluorescently labelled food.

Further, the vast majority of trophallaxis events were short in duration, possibly functioning to maintain the colony odour rather than disseminate food.

[11][12] Socially isolated workers rapidly lose weight, and exhibit reduced lifespans and behavioural changes including increased locomotion.

Camponotus fellah, like all tested carpenter ant species, harbours an intracellular endosymbiotic bacteria from the genus Blochmannia.

This endosymbiont contributes to host nutrition by recycling nitrogen into aminoacid biosynthesis, and when levels are experimentally reduced colony growth decreases.

This is particularly true of Carpenter ants, and C. fellah workers can be trained to associate odours with gustatory reinforcers in lab conditions.
