Barbary harvester ant
BeginnerMessor barbarus
Messor barbarus is a granivorous harvester ant native to the Mediterranean region and a staple species in antkeeping. They feature distinct polymorphism with large, often reddish-headed major workers capable of cracking tough seeds. Colonies primarily feed on seeds to produce "ant bread", but also require insect protein for brood development alongside separate dry and humid nest chambers.
