What kind of ants are in my Ant Mountain™?Updated a month ago

Insect Lore provides Western Harvester Ants (Pogonomyrmex occidentalis). Here are some fun facts about Harvester Ants! 

• These hardy ants come from the rugged desert hills of the American Southwest.
• They are called Harvester Ants because they gather seeds, dead insects and other food items.
• They live in very dense colonies inside an ant hill.
• They prefer to build their nests in a sunny location. 
• Like butterflies, ants go through complete metamorphosis and the four stages are egg, pupa, larva, and adult.
