Which statement about big headed ants is accurate?

• A. They have two distinct worker forms
• B. They are always indoors
• C. They feed exclusively on sugar
• D. They do not form nests

Answer: (A)

Big-headed ants show worker polymorphism, meaning their workers come in two distinct forms. The major workers have disproportionately large heads and strong jaws, functioning like soldiers to defend the nest and process larger seeds, while the minor workers are smaller and handle foraging, brood care, and daily nest maintenance. This split in worker roles is a hallmark feature and explains why the statement about two distinct worker forms is accurate.

They aren’t confined to indoors; nests are typically outdoors—in soil, under mulch, or in rotted wood—but foraging ants can wander into structures. They don’t feed exclusively on sugar; their diet includes a mix of carbohydrates, proteins, and fats from various sources. And they do form nests, often sizable and complex, sometimes with multiple queens in invasive populations.
