When and Why Do Ants Have Wings and Fly?

While many people are surprised to learn that ants can fly, some species do indeed develop wings and take to the air. This aerial phase is not a universal trait for all ants within a colony, nor is it a permanent state. The presence of winged ants is a natural part of their life cycle, serving a specific and temporary purpose in their reproduction and colony expansion.

Not All Ants Fly

The ants commonly seen foraging for food, known as worker ants, are typically wingless. Only specific reproductive members of an ant colony, referred to as alates, develop wings. These alates include virgin queens and male ants. This winged stage is temporary for queens and a defining, though brief, characteristic for males.

These specialized ants are produced by mature colonies when conditions are suitable for reproduction. The development of wings signifies their readiness for a crucial reproductive event.

The Purpose of Flight

The primary reason for winged ants to fly is to participate in a synchronized reproductive event known as a “nuptial flight” or mating flight. This event involves virgin queens and males from various colonies taking to the air to meet and mate. The flight ensures genetic diversity by facilitating mating between individuals from different nests, which is crucial for the health and adaptability of ant populations.

Environmental cues, such as warm and humid conditions, can trigger these mass synchronized flights. This coordinated emergence also provides safety in numbers, making it more difficult for predators to target individual ants. The nuptial flight is a fundamental step for the establishment of new ant colonies, as it allows mated queens to disperse and found their own nests.

Life After the Nuptial Flight

After the mating flight, the fate of the winged ants diverges significantly. Fertilized queen ants will shed their wings, as they are no longer needed for flight. The queen then seeks a suitable location to establish a new colony, often digging an underground chamber to lay her first batch of eggs. She will nurture her initial brood of worker ants, relying on stored energy until they mature and can forage for the colony.

In contrast, male ants have fulfilled their reproductive purpose during the nuptial flight and typically die shortly after mating. Their existence is primarily dedicated to the fertilization of new queens. This temporary nature of flight and differing outcomes for males and females highlight their distinct roles in species continuation.

Flying Ants vs. Termites

Flying ants are often confused with winged termites due to their similar appearance during swarming events, but distinct physical characteristics differentiate them. Flying ants have a distinctly pinched waist, creating a segmented body appearance. Their antennae are bent or “elbowed”.

In terms of wings, flying ants possess two pairs that are unequal in size, with the front wings typically larger than the hind wings. Termites, conversely, have a broad waist that gives their body a more uniform, tube-like shape. Their antennae are straight, often appearing bead-like. Furthermore, winged termites have two pairs of wings that are equal in size and length.
