Did you think that ants were just pesky little critters that invade your kitchen each summer? You might be surprised to learn how much there is to know about these fascinating creatures like the Big Headed Ants. So, if you’re looking for some unusual trivia to impress friends at your next gathering, or you’re simply in the mood to expand your knowledge of the natural world, you’re in the right place!


  • Big Headed Ants are not harmful to humans, but can be a nuisance and damaging to environment
  • They are characterized by their large heads and are one of the world’s invasive species
  • They can create supercolonies and contribute to the decrease of native species
  • They are known to farm other insects for their own benefit

The Buzz About Big Headed Ants

The Big Headed Ant (Pheidole megacephala) is a species of ant easily identifiable by its soldier ants’ disproportionately large heads. These tiny critters, which range in color from yellow-brown to reddish-brown, thrive in subtropical and tropical regions. It is one of the most invasive ant species in the world, numbering in thousands per colony, and has little trouble adapting to new environments.

Despite their large heads, Big Headed Ants are not known to be harmful to humans. They neither sting nor bite, although they can be a nuisance when they invade human habitats. However, their feeding habits can cause damage to your plant life, so you might not want to roll out the welcome mat too eagerly!

A Super Species Indeed

These ants are far more fascinating than they might seem at first glance. Their undeniable ability to drive out local species and claim areas for their own supercolonies is worryingly enchanting. They are known to be extremely competitive, meaning that once a Big Headed Ant colony sets up shop, it can often result in the decrease of native ant species.

But the term ‘super’ is not used lightly here. The term ‘supercolony’ refers to the vast networks of interconnected nests that these ants create, housing millions of workers and allowing them to dominate areas quickly. This isn’t an exaggeration – one supercolony was found stretching 3,700 miles across southern Europe!

Benevolent Farmers or Cunning Masters?

Beyond just being a super competitor, the Big Headed Ant is also known for its ‘farming’ practices. Sounds cute, right? Well, it’s actually more of a cunning survival strategy. These ants ‘farm’ other pests such as aphids, scale insects, and whiteflies, protecting them from predators and milking them for honeydew, a sweet substance these insects produce.

This symbiotic relationship provides a steady supply of food for the ants, but is not exactly beneficial for your garden plants. Indeed, the increase in numbers of these farmed pests can cause extensive damage, making Big Headed Ants somewhat less of the ‘small, harmless creature’ they first appear to be. Now isn’t that an interesting plot twist?
