When you think of a harvester ant, you might imagine a hard-working insect diligently collecting food for its colony. Harvester ants are a fascinating group of ants known for gathering seeds, creating distinct mounds, and defending their colonies with painful stings, but how much do you really know about them?
Keep reading to learn everything you need to know about harvester ants while comparing them to other ant species and offering insights into how to get rid of these pesky insects if they invade your space.
What Is a Harvester Ant?
A harvester ant is a type of ant that primarily collects seeds to feed its colony. These ants belong to various genera, including Pogonomyrmex, which is one of the most well-known in the southwestern United States. They are ground-dwelling insects, typically found in open, dry areas like deserts, grasslands, and scrublands.
These ants are named for their harvesting behavior. They’re most often gathering seeds and sometimes dead insects to bring back to their nests. Their colonies can be extensive, and their presence is usually indicated by noticeable harvest ant mounts—clearings of vegetation with a crater-like entrance in the center.
The social structure within a harvester ant colony is complex and highly organized. Colonies consist of a queen, worker ants, and, on occasion, winged reproductive males and females. Workers are responsible for foraging, defending the nest, and caring for the young. Communication within the colony is largely chemical, involving pheromones that signal everything from danger to food sources. This efficient system allows the colony to function cohesively and respond to environmental threats or opportunities almost instantly.
What Do Harvester Ants Look Like?
Depending on the species and region, harvester ants vary in color from red to brown or black. A fully grown harvester ant is about ¼ to ½ inches long, making it relatively large compared to other ants.
Harvester ants have a segmented body with a large head, powerful mandibles, and a smooth thorax. Their large mandibles are used for carrying seeds and other food items. Some species, such as the western harvest ant, have a beard-like structure called a psammaphore beneath their head that helps with carrying fine particles like sand or seeds.
Where Are Harvest Ants Found?
They are most commonly found in the western and southern United States, particularly in arid and semi-arid regions. The western harvester ant, for instance, is widespread in states like Nevada, Arizona, New Mexico, and Texas. They thrive in open, sunlit areas with sandy or loose soil where they can construct elaborate underground tunnels.
Their range also extends into parts of Central and South America, but in the U.S., they’re a familiar presence in desert and prairie environments.
What Do Harvester Ants Eat?
As their name suggests, they collect and consume seeds, making them important seed dispersers in some ecosystems. However, they aren’t strict vegetarians. Harvester ants may also eat dead insects and other organic material. Their preference for seeds can sometimes lead them to become pests in agricultural or landscaped areas.
They store seeds in chambers underground, and these stored supplies can sustain the colony through droughts or food shortages. Interestingly, the act of seed collection has ecological consequences beyond the colony itself. By dispersing seeds, harvester ants contribute to plant propagation and can influence plant community structures in grasslands and deserts. This behavior makes them both a beneficial insect in the wild and a problematic one in manicured environments like gardens, golf courses, and farms.
Do Harvester Ants Bite?
Yes, but unlike many ants that bite and spray acid, harvester ants both bite and sting, making encounters with them quite painful. When they bite, they inject venom, which can cause a burning sensation, swelling, and localized pain that lasts several hours or even days.
The real threat, however, is their sting, which they administer after latching on with their mandibles. Reactions vary by individual, but in rare cases, allergic responses can occur. While deaths from harvester ant stings are extremely rare, an allergic reaction could potentially be life-threatening without immediate medical intervention.
Carpenter Ants vs. Harvester Ants
The key distinction between harvester ants and carpenter ants lies in their nesting and feeding habits. Carpenter ants nest in wood, including homes and other structures, making them a significant pest in urban areas. Harvester ants, on the other hand, nest underground and are more of an outdoor nuisance.
Carpenter ants don’t sting but can bite, while harvester ants both bite and sting. They may look similar in size, but their damage potential and behavior are quite different.
How Long Do Harvester Ants Live?
Worker ants typically live for a few months, but the queen can live for several years (sometimes up to 15 years or more!). Queens are responsible for reproducing and ensuring the colony’s survival over time.
