Efficiency of foraging behavior in the ant genus Messor (Hymenoptera: Formicidae: Myrmicinae) in response to food distribution

open access: yesEuropean Journal of Entomology, 2023
Harvester ants are known to be species that collect seeds of plants and store them in underground chambers. Workers forage solitarily or in groups, and the intensity of their foraging depends, among other things, on the rate of food intake.
