The socially exchanged fluid passed mouth-to-mouth during trophallaxis contains molecules that can influence development, potentially mediating communal control of colony phenotypes.

A mathematical model predicts the precise conditions for natural selection to favor the evolution of non-reproductive workers in insect colonies with haplodiploid genetics.

Chemical nestmate recognition in honey bee colonies depends on an innate, socially modulated developmental process.

Body shape and behavioural specializations found across the castes of ant species evolved together and reflect different abilities for ground behaviors.

Colony satiation level determines the unloading rate of laden foragers, which, in turn, rely on their own food load to adjust their foraging effort.

Ants employ a new kind of trail to resolve group-level navigational difficulties in scenarios where the information available to individuals does not suffice.

After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.
