Omnivorous; they consume a variety of foods including fats, proteins, and sugars, and are known to scavenge dead insects.

Behavior Patterns

Notable for 'budding' (forming new colonies when stressed or poisoned) and multi-queen social structures; they are highly persistent and forage along defined trails.
