The males soon die and the fertilized females lose their wings and start a new colony. However, very few queens are successful at starting their own colonies and very few are actually able to mate.

In the first, the female-calling syndrome , the females, which are often wingless and sometimes just fertile workers, do not travel far from the nest. Standing on the ground or low vegetation, they release sex pheromones to "call" the winged males to them Figure In general, the colonies of female-calling species are typically small at maturity, with 20 to 1, workers, and produce relatively few reproductives.
So far as known the females mate only once. An unusual variation on this pattern is followed by the Florida harvester ant Pogonomyrmex badius. Females gather on the surface of their home nest and are inseminated by males; afterward they fly off to start new colonies. Van Pelt thought that the males came from the same nest as the females with whom they copulate, but S. Porter personal communication observed that they usually fly for about a quarter-hour first before settling on a nest different from their own.
Porter observed one case in which a male mated with two females after alighting. The second combination of traits during mating is the male-aggregation syndrome. Males from many colonies gather at specific mating sites, usually prominent features of the landscape such as sunflecked clearings, forest borders, hilltops, the crowns of trees, and even the tops of tall buildings. Sometimes, as in some species of Lasius and Solenopsis , the males cruise in large numbers at characteristic heights above the ground.
The females fly into the swarms, often from long distances, in order to mate see Figures through and Plate 2 , and afterward they typically disperse widely before shedding their wings and excavating a nest. The winged queens and males of the fire ant Solenopsis invicta , for example, fly up to heights of meters or more; 99 percent then descend to the ground within a 2-kilometer radius of their origin, while a very few travel as far as 10 kilometers.
The ability of a single mature colony to disseminate fertile queens in many directions over long distances is one of the reasons the fire ant is so difficult to eradicate Markin et al.
Male-aggregation species typically differ from those utilizing female calling in two other key respects: the mature colonies are large, containing from several thousand to over a million workers and producing hundreds to thousands of reproductive adults yearly, and multiple insemination is common. An unusual reversal of the usual swarming procedure was recently discovered in some Pheidole species of the southwestern United States: the winged queens gather in aerial swarms, where they maintain a more or less uniform distance from each other while attracting males with pheromones.
Swarms of variable composition, some predominantly male and others predominantly female occasionally exclusively female , have been reported by Eberhard in the coccid-tending formicine Acropyga paramaribensis of northern South America.
Ant species can be classified another way into two broad types. When the males alight on the surface of the mating site, either in response to female calling or in swarms to compete directly with one another, they are often typically large and robust in form and possess well-developed mandibles. In contrast, males that gather in aerial swarms are usually but not invariably smaller relative to the queen than are males of the first type.
Also, their mandibles are reduced in size and dentition, sometimes consisting of nothing more than vestigial lobate or strap-shaped organs.
An example of this type is the small myrmicine Pheidole sitarches of the southwestern United States. Up to 50 males form circular swarms that hover from a few centimeters to two meters above the surface of woodland clearings. The virgin queens fly in slow, even circles through the aggregations until mounted in midair by a male, whereupon the pair cease flying and spiral to the ground together to complete the copulation Wilson, b.
The swarms of some ant species are among the more dramatic spectacles of the insect world. Froggatt in Wheeler, c describes the flight of the giant Australian bulldog ant Myrmecia sanguinea as follows:. Roul, an isolated, flat-topped, basaltic hill, which rises about feet above the surrounding open, cleared country.
The summit, about half an acre in extent, is covered with low "black-thorn" bushes Bursaria spinifera. I saw no signs of bull-dog ant nests till I reached the summit. Then I was enveloped in a regular cloud of the great winged ants. They were out in thousands and thousands, resting on the rocks and grass. The air was full of them, but they were chiefly flying in great numbers about the bushes where the males were copulating with the females.
As soon as a male and there were hundreds of males to every female captured a female on a bush, other males surrounded the couple till there was a struggling mass of ants forming a ball as large as one's fist. Then something seemed to give way, the ball would fall to the ground and the ants would scatter.
As many as half a dozen of these balls would keep forming on every little bush and this went on throughout the morning. I was a bit frightened at first but the ants took no notice of me, as the males were all so eager in their endeavors to seize the females. Donisthorpe tells of the mass flights of the abundant Myrmica rubra from the distinctively British viewpoint of an earlier observer:. The effect of those in the air--gyrating and meeting each other in their course, as seen against the deep blue sky--reminded him of the little dodder, with its tiny clustered blossoms and its network of ramifying scarlet threads, over the gorse or heather at Bournemouth.
He noticed the swarm about thirty paces off, and it began to assume the appearance of curling smoke; at forty paces he could quite imagine the tree to be on fire. At fifty paces the smoke had nearly vanished into thin air. A still different mating pattern was described in the Australian formicine species Notoncus ectatommoides by W.
Brown a :. From these holes, males began to issue almost immediately in numbers, until within a few minutes there had accumulated on the surface a surprisingly large number of this sex and also a few workers. The males traveled aimlessly over the sward in low, flitting flight from one blade of grass to another, never rising more than a foot or so from the ground.
Movement seemed to take place at random in all directions. Suddenly, however, the males of one area all rushed simultaneously to a single focal point, which proved to be a winged female emerging from a small hole. In a few seconds, the female was surrounded by a dense swarm of males in the form of a ball, which at times must have exceeded 2 cm in diameter. This ball moved in a half-tumbling, half-dragging motion over and among the densely packed grass blades, and held together for perhaps 20 seconds, after which the female escaped, flying straight upward.
She appeared not to be encumbered by a male, and no males were seen to follow her for more than a foot above the ground; she flew steadily, and soon passed out of sight. Meanwhile, the lawn had become dotted with similar balls of frenzied males, each surrounding a female in a fashion similar to the first. Obviously, many more males than females were involved in this particular flight.
On each occasion, the female left the ball after seconds and flew straight upward. In a similar fashion males and females of Formica obscuripes conduct nuptial swarms on the ground. Talbot observed them flying to "swarming grounds" near their nests which were maintained throughout the nuptial flight season and perhaps even from year to year.
The males fly back and forth above the ground searching for females which "stand on grasses, forbs or bushes," and apparently signal their presence to the males by pheromones. No encompassing theory exists to explain the extreme variation in the patterns of mating behavior so far observed. However, a close examination of individual species reveals details that clearly contribute to the greater success of the sexual castes. For example, flying queens of the formicine Lasius neoniger stay strictly within open fields, the exclusive habitat of the earthbound colonies.
Fewer than one percent make the mistake of venturing into adjacent woodland, a habitat dominated by the otherwise closely similar Lasius alienus. In one experimental study Wilson and Hunt, , newly inseminated and flightless queens were labeled with radioactive material for easy tracking and displaced to woodland sites.
They attempted to crawl out but were unable to do so. In other words the Lasius queens depend on controlled flight patterns to survive. Like orientation, the timing of the flights is important for successful mating and colony foundation.
Flights conducted as part of the female-calling syndrome do not appear to be well synchronized at the level of either the colony or the population of colonies. The search by airborne males for solitary calling females in fact resembles that of many solitary wasps Buschinger, ; Haskins, In contrast, flights leading to male aggregation are tightly synchronized within the colony as well as among colonies of the same species.
The manner in which this coordination is achieved is typified by Pogonomyrmex harvester ants of the southwestern United States. Just prior to take-off, males and females move restlessly in and out of the sandy crater nests or gather in clusters around the entrance, as shown in Figure This preflight activity is especially pronounced in Pogonomyrmex maricopa , a morning flyer, the queens and males of which evidently need more time to warm up before taking wing.
As the time of departure approaches, the reproductives run back and forth in mounting intensity. Now, in a frenzy, they climb up and down on grass leaves or small bushes around the nest.
At this point many more workers pour out of the nest, running excitedly around the nest and attacking any moving object encountered including the careless myrmecologist. When the first reproductives try to take flight, the workers at first delay many of them by pulling or carrying them back to the nest. However, once the flight is in full progress, workers cease to interfere.
Although the timing of the take-off overlaps considerably between the two sexes, the males generally fly from the nest first. Once aloft both sexes appear at first to drift with the wind, but after a few seconds they take a course upwind or across the wind. Soon afterward they arrive at the swarm sites, centered on conspicuous landmarks such as tree crowns and the tops of hills or in the case of Pogonomyrmex rugosus merely flat local areas in the desert.
A similar marching order is observed by the carpenter ant Camponotus herculeanus , which nests in the trunks of both living and dead trees in the boreal forests of Eurasia and North America.
Males leave before the queens, although the periods broadly overlap. The early departure of the winged forms is inhibited by the workers, who drag or carry many back to the nest entrance Figure However, when the males do succeed in taking flight, they discharge a pheromone from their mandibular gland.
The concentration of this substance is highest at the peak of male activity--the gland emission can now be smelled readily by humans--enough to trigger the mass take-off of the females Figure Blum b reports methyl 6-methylsalicylate and mellein as two of the three components of the secretion.
This pleasantly aromatic combination is shared by most other species of Camponotus , but considerable differentiation nevertheless is achieved by the addition of other substances, such as octanoic acid and methyl anthranilate, according to species see also Lloyd et al.
A similar function may be accomplished by vibrational signals rather than pheromones in Pogonomyrmex harvester ants. Both males and virgin queens stridulate just before and during take-off, running the sharp posterior rim of their postpetiole over the actively moving, striated file on the first gastric tergite Markl et al.
Many entomologists, including especially Kannowski a, and Weber , have observed that each ant species, at least those displaying the male-aggregation syndrome, swarms at a precise time in the hour diel cycle; and the time differs among species. Under controlled laboratory conditions, McCluskey , , , and McCluskey and Soong demonstrated in fact that the rhythms of males are generally if not universally circadian and endogenous. Once set in a laboratory regime of 12 hours light alternating with 12 hours dark, the rhythms persist for up to a week in total darkness.
They are also quite precise. Throughout the remainder of the hour cycle they are quiescent, usually stirring themselves only to groom, solicit food from the workers, or walk sluggishly about the nest. Males of the Argentine ant Iridomyrmex humilis , in contrast, are most active at the very end of the light period. Similarly distinctive rhythms, each spanning only one or two hours, have been documented by McCluskey and his co-workers across a wide diversity of species from four subfamilies Ponerinae, Myrmicinae, Dolichoderinae, and Formicinae , including some that are wholly nocturnal.
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.

There is also anecdotal evidence that flying ant days often occur after some summer rain. Where do flying ants come from? Why do ants fly? Why do ants swarm? During this brief, once-in-a-lifetime mating period, a queen usually mates with several males.
What happens after the nuptial flight? The ants you see the rest of the year are female workers, gathering food for the colony. How long do flying ants live? Why flying ants are actually a good thing These flying insects may seem annoying to some people, but their tunnelling activities play a vital role in improving soil quality. Ants in the UK Ants, along with bees and wasps, belong to the insect group called Hymenoptera.
There are about 60 species of ant in the UK, and they all live in complex colonies. Do red ants fly?
