The honeybee waggle dance: how a bee tells her sisters where the flowers are
A bee comes back to the hive and dances in the dark. The angle of her dance shows the flowers' direction from the Sun, and how long she waggles shows how far away they are. You can read the dance on three real maps of Romania.
The bee on the comb is dancing for her sisters. Watch her, then tap the map where you think she is sending them.
Up on the comb means towards the Sun. If the bee waggles straight up, the flowers lie in the direction of the Sun.
The tilt shows which side of the Sun. A run tilted 40° to the right of vertical means flowers 40° to the right of the Sun's direction, seen from the hive.
How long she waggles shows how far. The ruler under the comb fills while the bee waggles; the rings on the map show what distance each length means.
Dance:
In the hive
On the map
No map: type the angle and the distance
The hives are models placed near Viscri, Breb and in Bucharest. The land areas on the map come from OpenStreetMap; the flowers are a scenario. What is measured and what is imagined: below.
The dancer walks across the vertical comb and shakes her body from side to side several times a second. Then she loops back in a half circle and starts again, once on one side, once on the other. Each straight walk with the shaking is a “run”.
In the dark hive, “up” stands for the Sun. If the flowers lie 40° to the left of the Sun, the bee tilts her run 40° to the left of vertical; the example is von Frisch's (1973).
The farther the flowers, the longer the waggle. In von Frisch's bees, from about half a second for 200 m to about four seconds for 4.5 km. Over the first 1.7 km, the curve measured on one colony of Carniolan bees in Franconia, Germany (56 dances), climbs from 0.41 s at 100 m to 2.20 s at 1.7 km (Kohl and Rutschmann, 2021).

Eight things checked in the scientific papers, each with its source. Karl von Frisch, who decoded the dance, shared the 1973 Nobel Prize for discoveries about the social behaviour of animals.

244 Hz
The dance is read in the dark
Inside a hive it is dark. Her sisters crowd round the dancer and touch her with their antennae, and the comb vibrates while she waggles, at about 244 Hz (206 to 292 Hz, N = 11), weakly, around the threshold of what bees can sense. How scent, movement and vibration combine to give the angle and the distance is still debated.
Synthetic sound made for this page: the same 244 Hz tone, switched on and off at the rhythm of the waggle (13 a second), for as long as each waggle lasts. It is not a recording of a hive.
For food 230 m away, a waggle run averages 6.3 mm and lasts 0.44 s. The bee moves forward at 15 mm per second and shakes her body about 13 times a second (1,009 runs from 108 dances by 20 Carniolan bees; a review gives 15–25 Hz, Ai et al., 2019). Colonies and methods differ: at 230 m the curve in the game gives about 0.63 s, not 0.44 s. In the game the dance is drawn far larger.
In a first experiment, a colony new to the area danced for a tunnel only 6 m long as if the food were 262 m away (the authors' conversion from the number of waggles in a run): bees seem to gauge distance by how fast the scenery streams past their eyes. Once the bees had explored the surroundings, the effect disappeared: familiar landmarks cancelled it.
Through the day, the direction of the dance changes by the same angle the Sun has travelled, in the opposite sense. That is why each of the three dances in the game is read with the Sun in a different place, calculated for its location and time.
A bee that met danger at a flower can head-butt a dancer and give a brief buzz, at 380–410 Hz. The dancer tends to stop. The signal is no part of the dance: it means “stop”. Bees attacked at a feeder produced 43 times more of these signals.
A swarm looking for a home sends out scouts, and they dance for the cavities they found. Scouts seem to sense that the decision is made when 10–15 or more of them are at the same cavity at once. A swarm prefers cavities above 20 litres, with a small entrance (under 30 cm²), facing south. Scouts use “stop” signals to silence dancers for rival sites.
Researchers in Britain decoded 5,484 dances of bees from a hive at the centre of a 94 km² area and mapped where the dances said the bees were foraging. The bees favoured land under the highest tier of UK agri-environment schemes and avoided land under the basic organic tier. Researchers decode dances the way you do in the game, only at scale.
For decades some biologists argued that bees find food by smell, not by the dance. Followed by radar, recruits fly roughly in the direction of the dance and then search around. In a 2023 test, 3 of 47 bees released from the hive reached an unscented feeder 384 m away, and none of the bees displaced elsewhere did; the authors say most likely because of the unnatural, unscented feeder, and the bees still flew roughly in the direction of the dance. The scent on the dancer matters too.
Romania's honeybee is usually called Apis mellifera carpatica. Its standing as a subspecies is debated. Ruttner split Romania between the Carniolan bee inside the Carpathian arc and the Macedonian bee outside it (as recounted by Tofilski et al., 2021). In one genetic test, part of the Romanian and Moldovan reference samples grouped with Carniolan bees and the rest with Macedonian-type bees (Momeni et al., 2021). Wing measurements show two populations, one on each side of the Carpathians (Tofilski et al., 2021).
As far as we could find, their dance has not been measured. Searches on 2 October 2026 in Europe PMC, OpenAlex and Crossref found no calibration study on Carpathian bees. The game uses the curve measured on close relatives, Carniolan bees in Germany, between 100 m and 1.7 km (Kohl and Rutschmann, 2021). That our bees dance the same way is an assumption. Even within one hive each bee has her own calibration: a dancer and a recruit can misread the distance by up to 50% (Schürch et al., 2016).
Romania had about 2.4 million declared hives in 2023, among the top three countries in the European Union by number of hives (European Commission, January 2026 edition). Eurostat's farm statistics, which count only hives on agricultural holdings, give 1.7 million.

The distance–duration curve: Carniolan bees, between 100 m and 1.7 km (Kohl and Rutschmann, 2021). It is not extended beyond that range: the centre of every flower patch in the game lies between 300 m and 1.65 km.

Imagined by us
The hives: three model hives, placed near the villages of Viscri and Breb and in Bucharest. They are not real apiaries.
The flowers: a circle with a radius of 150 m inside an area OpenStreetMap labels meadow, orchard, farmland or park. We did not check what is in bloom there on that day.
The spread of the dance: the runs on screen deviate by about 12° around the true direction (the 11.6° is our conversion of the κ = 24.9 parameter in Couvillon et al., 2014; the dance in the game is more precise than the one Landgraf measured) and by 0.15 s in duration. In Carniolan bees at 230 m, the standard deviation of a run's angle was 25° (by direction of movement) and 28° (by body orientation) (Landgraf et al., 2011).
The drawing: the bees are far larger than life, and the dancer's body moves on screen 6.5 times a second, not 13. The sound of the comb is synthetic.
The dotted circle after your answer shows what a 12° deviation means on the map at that distance: the tolerance of the game. It does not show where real recruits land.
A dance in which a bee that has returned to the hive shows her sisters where she found flowers. Karl von Frisch decoded it. He shared the 1973 Nobel Prize in Physiology or Medicine with Konrad Lorenz and Nikolaas Tinbergen, for discoveries about the social behaviour of animals.
How do bees show direction?
By the angle of the waggle run from vertical. On the vertical comb in the dark hive, “up” stands for the Sun, so the angle from vertical is the angle between the Sun and the flowers.
How do bees show distance?
By how long the waggle lasts. In one colony of Carniolan bees in Germany, a run averaged 0.41 s for flowers 100 m away and 2.20 s for flowers 1.7 km away. The curve differs from bee to bee and may depend on what the bee sees on the way.
Do Romanian bees dance the same way?
We found no study that measured the dance of Carpathian bees. The curve in the game comes from Carniolan bees in Germany.
