Each summer, there comes a moment when we suddenly notice that the ground is crawling with large winged ants. Then the air seems to be full of them and we find ourselves ducking and diving, trying not to get them in our mouths or hair.
Flying ants are known as alates. In the UK, particularly in urban areas, the winged insects you see are almost always the sexually mature queens and males of the black garden ant, Lasius niger. The larger ants are the queens. They can be up to 15mm long.
This annual swarming event usually occurs in July or August and coincides with a period of hot and humid weather. Winged ants appear at different times around the country and local weather conditions are critical for the coordination of swarming activity.
It can be unfortunate timing for tennis players at Wimbledon. There are years when flying ants plague players during their matches, causing so much disruption it makes the news. However, swarms of flying ants can appear any time between June and the start of September.
A multi-year citizen science project by the Royal Society of Biology found that the widely held idea of a 'flying ant day' is actually a misconception: there is no single day when ants fly all at once. Rather, there is a 'flying ant season'. Winged ants actually emerge over several weeks, although there are often several peaks in appearances, each lasting only a few days. The precise pattern of swarming varies from year to year.
Black garden ants nest in dry soil. You'll often find them in flower beds and lawns, and under paving slabs or stones. Patios are a favoured location. They are common in almost any dry, open area that is warmed by the Sun - including gardens, pavements, brownfield sites, heathland, grassland and coastal areas.
Ants live in a caste system, where individuals have specific jobs. The queen lays the eggs while female workers look after the queen, eggs and larvae. They also gather food, enlarge the nest and otherwise ensure the colony runs smoothly. Most of the eggs develop into workers, but when the colony is ready, the queen begins to produce virgin queens and males.
An ant colony can only expand so much. At some point a new queen will need to strike out on her own to begin a new colony. She needs to meet and mate with a male from a different colony and find a new area in which to start building her nest. Growing wings and flying enables her to do this.
Once ants have mated, the role of the males is over. The mated queens quickly chew off their own wings and begin looking for a suitable site in which to nest and set up a new colony. This is why you often see large ants walking around after a 'flying ant day' and may even see discarded wings scattered over pavements.
Once the queen has found a suitable site, she digs herself an underground chamber and lays her first few eggs, which she rears to adulthood. She won't eat for weeks - not until her first brood of daughter workers are ready to forage for food for her.
The stock of sperm the queen received during the nuptial flight will enable her to lay fertilised eggs for the rest of her lifetime. And she has many egg-laying years ahead of her, often reproducing until a colony is thousands strong (large nests can have more than 20,000 workers).
Males don't do any work in the nest and are only produced by their colony during flying ant season. They develop from unfertilised eggs. After the nuptial flight, the male ants usually only live for another day or two, so not much more than a week in total. Their sole reason for existence is to mate with new queens.
Lasius niger queens can generally live for up to 15 years (although L. niger queens in captivity have reached 28 years). But they spend most of their lives in their nest. They only spend a small portion of their lives as winged or flying ants - when they are young queens that need to establish a new colony of their own.
The black garden ant and the related cornfield ant (Lasius alienus) are particularly important to the continued survival of the silver-studded blue butterfly (Plebejus argus) on heathland. Populations of this attractive butterfly have declined across most of its range.
The ants and the butterfly have developed a mutually beneficial relationship. The ants tend the caterpillars, protecting them from predators. In return, the ants feed on secretions produced by the caterpillars.
The nuptial flight is an important phase in most - but not all - ant species' reproduction. Red ants (Myrmica rubra) are among the other common ant species in Britain that grow wings and swarm. However, in the flying ant surveys conducted by the Royal Society of Biology, nearly 90% of the winged ants observed were black garden ants (Lasius niger), also often called the common black ant.
The types of ant you see flying will depend on where you are. For example, in woodland you may see wood ants. All ants require good weather to fly, with no rain or wind. The temperature and humidity that triggers swarming and flight is different for each species, so the timings of their nuptial flights will vary.
British wildlife is under threat. The animals and plants that make our island unique are facing a fight to survive. Hedgehog habitats are disappearing, porpoises are choking on plastic and ancient woodlands are being paved over.
For many, the Museum is a place that inspires learning, gives purpose and provides hope. People tell us they 'still get shivers walking through the front door', and thank us for inspiring the next generation of scientists.
To reverse the damage we've done and protect the future, we need the knowledge that comes from scientific discovery. Understanding and protecting life on our planet is the greatest scientific challenge of our age. And you can help.

The rule for operating unmanned aircraft systems (UAS) or drones under 55 pounds in the National Airspace System (NAS) is 14 CFR Part 107, referred to as the Small UAS Rule. However, if you want to fly a drone for purely recreational purposes, there is a limited statutory exception ("carve out") that provides a basic set of requirements.
Many people assume that a recreational flight simply means not flying for a business or being compensated. But, that's not always the case. Compensation, or the lack of it, is not what determines if a flight was recreational or not. Before you fly your drone, you need to know which regulations apply to your flight.
The Exception for Limited Recreational Operations of Unmanned Aircraft (USC 44809) is the law that describes how, when, and where you can fly drones for recreational purposes. Following these rules helps keep people, your drone and our airspace safe:
Fly at or below 400 feet in Class G (uncontrolled) airspace.
Note: Anyone flying a drone in the U.S. National Airspace System (NAS) is responsible for flying within the FAA guidelines and regulations. That means it is up to you as a drone pilot to know the rules: Where Can I Fly?
Have a current FAA registration, mark (PDF) your drones on the outside with the registration number, and carry proof of registration with you when flying.
Note: Beginning September 16, 2023, if your drone requires an FAA registration number it will also be required to broadcast Remote ID information (unless flown within a FRIA). For more information on drone registration, visit How to Register Your Drone.
Notice: We make every effort to keep Fly-Rights up to date, but airlines frequently change the way they do business. So by the time you read this, a few procedures we explain may be different.
The elimination of government regulation of airline fares and routes has resulted in lower fares and a wide variety of price/service options. In this new commercial environment, consumers have had to take a more active role in choosing their air service by learning to ask a number of questions:
Because of the emphasis on price competition, consumers may choose from a wide variety of air fares. It is easy to compare fares and schedules on the Web, using airline web sites or third-party reservation services. You can also contact a travel agent, another ticket outlet, or the airlines serving the places you want to travel to. (Some airlines and other outlets charge a fee for tickets purchased by means other than the Web. On the other hand, a few airlines may charge a fee for tickets that are purchased via the Web.) You can also be alert to newspaper and radio ads, where airlines advertise many of the discounts available in your city. Finally, be alert to new companies serving the market. They may offer lower fares or different services than older established airlines. Here are some tips to help you decide among air fares:
Once you decide when and where you want to go, and which airline you want to use, you will usually have to purchase a ticket in order to hold a confirmed seat. However, many large airlines will hold a reservation for 24 hours or so without payment. Others require payment at the time you make a reservation but will provide a full refund if you cancel in the first day or so. When available, both of these procedures permit you to hold a seat and a fare for a short time while continuing to shop for a better deal. Be aware of the following considerations when selecting a flight and buying a ticket:
NOTE: In some cases tickets purchased overseas in foreign currency can only be refunded in that same currency and country, due to foreign government monetary restrictions. Keep this in mind if you are considering buying a ticket in a foreign country.
