Antennation of nectar-receivers encodes colony needs and food-source profitability in the ant Camponotus mus

In social insects, interactions among individuals are important in colony organisation because they can be used in decision making. During trophallaxis in ants, antennal and foreleg contacts between both partners are established. It has been suggested that a modulatory communication channel could be...
