A queen ant serves as the reproductive foundation of an ant colony, responsible for laying all the eggs that give rise to workers, soldiers, and future reproductive ants. Distinct from foraging worker ants, their successful capture is often the first step for individuals interested in antkeeping and establishing their own colony.
Identifying a Queen Ant
Distinguishing a queen ant from other colony members, such as male ants or larger workers, involves observing several key physical characteristics. Queens possess a significantly larger thorax, the middle section of their body, which is built to house the powerful flight muscles used during their nuptial flight. While male ants also have wings, their bodies are typically much smaller and more slender in comparison to a queen’s robust form. After mating, queen ants often shed their wings, leaving behind noticeable wing scars on their thorax, which are clear indicators of their reproductive status.
The overall size of a queen ant is generally larger than that of the worker ants from the same species, though this can vary. Her gaster, or abdomen, is also usually more developed and often appears swollen, as it contains her reproductive organs and developing eggs. These features—a disproportionately large thorax, the presence of wing scars, and a larger, more rounded gaster—are reliable methods for identifying a queen ant in the field.
When and Where to Find Queens
The most opportune time to find queen ants is during their nuptial flights, synchronized reproductive events where winged male and female ants emerge from their nests to mate. These flights are typically triggered by warm, humid days following rainfall. The moisture in the air and softened soil make it easier for queens to dig a new nest after mating. Depending on the species and geographical location, these flights can happen from late spring through early autumn.
After mating, newly fertilized queens descend to the ground to find a suitable location to establish a new colony. They can often be found walking across sidewalks, driveways, and open fields, particularly near sources of light like streetlights, which can disorient them. Searching in areas with sparse vegetation, under rocks, or near building foundations can also yield sightings, as queens seek sheltered spots to begin digging their initial claustral chamber.
Safe Capture Methods
Capturing a queen ant requires gentle handling to ensure her survival and success in founding a colony. The safest method involves using a small, clear container, such as a test tube, a small vial, or a clean plastic container with a lid. These items allow for the queen’s easy transfer without direct contact, which can stress or injure her delicate body. Avoid using fingers to pick up a queen, as this can damage her legs, antennae, or abdomen, compromising her ability to dig a nest or lay eggs.
To guide the queen into the container, place the opening directly in her path or gently nudge her towards it using a soft object like a small paintbrush or a piece of paper. Once she is inside, quickly but carefully secure the lid to prevent her escape. Minimizing stress and physical harm during capture is paramount for the successful establishment of a new ant colony.
Immediate Care After Capture
Upon successful capture, providing immediate care is crucial for the queen ant’s well-being and her ability to found a colony. The most suitable temporary housing is a “test tube setup,” which simulates a dark, humid, and secure underground chamber. This setup involves filling approximately one-third of a test tube with water, plugging the opening of the water section with a cotton ball to create a water reservoir, and leaving the remaining space for the queen. The cotton allows the queen access to moisture without drowning.
After placing the queen into the dry section of the test tube, plug the open end with another cotton ball, ensuring adequate ventilation while preventing escape. Do not offer food immediately, as newly mated queens rely on their stored fat reserves and the breakdown of their flight muscles for energy during the claustral period, when they do not forage. Place the test tube in a dark, quiet, and vibration-free location. This mimics her natural environment, reduces stress, and improves her chances of successfully laying eggs and raising her first brood of workers.
