Flying Ant Day is a fascinating natural phenomenon that occurs annually, typically in the summer, when large numbers of flying ants emerge at the same time.

Despite the dramatic headlines, flying ants are not harmful to humans. Their emergence is one of the world’s greatest – albeit most surprising – wildlife spectacles. So, let’s celebrate the day with 10 fun Flying Ant Day facts and one very bad joke.

10 fabulous Flying Ant Day facts

Annual event

Flying Ant Day refers to the day, or days, during the summer when large numbers of flying ants emerge simultaneously.

Nuptial flight

The event is part of the ants’ reproductive process, known as the nuptial flight, where male and female ants grow wings and take to the air to mate.

Timing and weather

Flying Ant Day typically happens after a period of wet weather followed by warm, humid conditions. This weather pattern provides optimal conditions for the ants to fly and mate.

Species involved

The most common species involved in Flying Ant Day in the UK is the black garden ant (Lasius niger), but other ant species also participate in similar events around the world.

Mass emergence

The synchrony in emergence is believed to increase the chances of mating success and reduce the risk of predation, as predators cannot consume all the ants at once.

Short-lived flight

The flying phase is brief. After mating, males typically die shortly after the nuptial flight, while mated females land, shed their wings, and start new colonies.

Ecological impact

The sudden appearance of large numbers of flying ants can have a significant ecological impact, providing a food source for birds and other predators.

Human perception

The mass emergence of flying ants can be a nuisance, particularly when they invade homes, outdoor activities or areas where food is present. But the good news is flying ants are harmless to humans – so, if possible, sit back and enjoy the spectacle.

Scientific interest

Researchers study Flying Ant Day to understand more about ant behaviour, reproductive strategies and the environmental factors that trigger these events.

Regional variations

Although the phenomenon is most famously observed in the UK, similar events occur worldwide, often involving different ant species and occurring at different times of the year depending on the local climate.

One (very bad) joke about Flying Ant Day

Why don’t flying ants ever get sick? Because they have tiny ant-bodies!
