| Description: |  |
desert-dwelling species of north- and middle america. They store seeds in up to 2m deep stores, making ant-bread out of it, similar as species of Messor. This is why they're so-called harvesting ants. In nature they're building huge subterraneously nests and tunnels. To be able to grind up hard seeds they have a brawny head with strong mandibles. |
