Which of the following organisms perform waggle dance for others of their kin to indicate the direction and the distance to a source of their food?

Result
Your answer:  ·  Correct: C
Explanation

The correct answer is Option 3: Honeybees.

The waggle dance is a sophisticated form of communication used by honeybees (specifically Apis mellifera) to inform their hive mates about the precise location of a food source. This behavior was famously decoded by the ethologist Karl von Frisch, who earned a Nobel Prize for his research.

  • Mechanism: The bee moves in a figure-eight pattern. The angle of the straight "waggle run" relative to the vertical hive wall indicates the direction of the food source in relation to the sun.
  • Distance: The duration of the waggle phase correlates with the distance to the nectar or pollen; longer dances signify further locations.

While butterflies, dragonflies, and wasps exhibit complex flight patterns, they do not utilize a symbolic "dance" to communicate coordinates to their kin. Therefore, Honeybees is the only scientifically accurate choice.

While recent research papers exist, this is effectively a 'Static Science' question disguised as current affairs. The 'Waggle Dance' is a Nobel Prize-winning discovery (Karl von Frisch, 1973) and a textbook example of animal communication. It rewards general scientific curiosity over rote textbook memorization.

How this question is built

This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.

Statement 1
Do honeybees perform a waggle dance to communicate the direction and distance to a food source to other members of their colony?
Origin: Web / Current Affairs Fairness: CA heavy Web-answerable

Web source
Presence: 5/5
"Honeybees search for food over many kilometers, and once a food source is identified they fly home along the shortest route and signal the direction and distance of the food source to their hive mates using a waggle dance"
Why this source?
  • Explicitly states that bees signal both direction and distance of a food source using the waggle dance.
  • Describes the behavior in the context of foraging and recruitment to hive mates.
Web source
Presence: 5/5
"close proximity to the dancing bee (followers) receive this information and some of them may be recruited to the same food source. On the vertical comb, the direction to a food source from the hive relative to the sun's azimuth is encoded according to the angle between an upward direction and the direction in which the dancing bee walks with her body waggling (waggle run)"
Why this source?
  • Explains how the waggle run encodes direction relative to the sun via the angle of the dance on the vertical comb.
  • Notes that nearby followers receive this information and may be recruited to the same food source.
Web source
Presence: 5/5
"One example is the honey bee waggle dance, which is performed by a forager bee to communicate the location of a good food source to another forager"
Why this source?
  • States that the waggle dance is performed by a forager to communicate the location of a good food source to another forager.
  • Frames the waggle dance as an example of social insect signaling conveying location information.

Strength: 5/5
“translocate to residues in pollen and nectar of treated plants. ,r;x -J) New research points out potential toxicity to bees and other beneficial insects through low level contamination of nectar and pollen with neonicotinoid insecticides used in agriculture. Although the low level exposures do not normally kill bees directly, they may impact some bee's ability to forage for nectar, learn and remember where flowers are located, and possibly impair their ability to find their way home to the nest or hive. In April 2013, the Luropean Commission decided to introduce a 2-year moratorium in EU on the 3 neonicotinod compounds-clothianidin, imidacloprid, and thiamethoxam-following reports by the European Food Safety Authority (EFSA) saying the substances pose an "acute risk" to honey bees essential to farming and natural ecosystems.”
Why relevant

Says sublethal pesticide exposure may 'impact some bee's ability to forage for nectar, learn and remember where flowers are located, and possibly impair their ability to find their way home', implying bees use learned spatial information in foraging.

How to extend

A student could combine this with basic knowledge that successful collective foraging in social insects often requires information transfer (e.g., about direction/distance) to ask whether bees relay spatial info via behaviors like a 'dance'.

Environment, Shankar IAS Acedemy .(ed 10th) > Chapter 6: Environmental Issues > Global warming > p. 119
Strength: 4/5
“Global warming causes flowers to bloom earlier or later than usual. When pollinators come out of hibernation, the flowers that provide the food they need to start to $e season has already bloomed. Pesticide (neonicotinoids, a neuroactive chemicaii It's not that the pesticides which are aimed at other insects are killing the bees outright. Rather that sublethal exposure of pesticides in nectar and pollen may be interfering with the honeybees internal radar, preventing them from gathering pollen and returning safely to the hive.”
Why relevant

Notes pesticides may interfere with the honeybees' 'internal radar', preventing them from gathering pollen and returning safely to the hive, indicating bees rely on internal navigation and possibly shared cues for foraging success.

How to extend

One could extend this by noting that if navigation is important to hive-level food collection, mechanisms for communicating location among nestmates (such as directional signals) would be plausible to investigate.

Geography of India ,Majid Husain, (McGrawHill 9th ed.) > Chapter 9: Agriculture > APICULTURE (BEEKEEPING) OR GOLDEN REVOLUTION > p. 91
Strength: 3/5
“Apiculture is the science and culture of honeybees and their management. Beekeeping (or apiculture, from Latin apis, a bee) is the practice of intentional maintenance of honey bee colonies, commonly in hives, by humans. A beekeeper (or apiarist) may keep bees in order to collect honey and beeswax, or for the purpose of pollinating crops, or to produce bees for sale to other beeskeeper. A location where bees are kept is called an apiary.”
Why relevant

Defines apiculture and lists reasons beekeepers keep bees (collect honey, pollination), implying organized, coordinated foraging by colonies to supply hive resources.

How to extend

Combine with the fact that large colonies need efficient ways to direct many workers to food patches to hypothesize existence of a recruitment/communication behavior (e.g., waggle dance) that encodes location.

Geography of India ,Majid Husain, (McGrawHill 9th ed.) > Chapter 9: Agriculture > The Colony of Bees > p. 93
Strength: 3/5
“A colony of bees consists of three classes of bee: a queen, which is normally the only breeding female in the colony; a large number of female worker bees, typically 30,000–50,000 in number; and a large number of male drones—ranging from thousands in a strong hive in spring to very few during death or cold season The production and consumption of honey in some of the selected countries of the world has been given in (Table 9.17).”
Why relevant

Describes colony structure with tens of thousands of worker bees, implying division of labor and the need to coordinate many workers' activities like foraging.

How to extend

A student could reason that coordination among many workers would benefit from explicit signals conveying distance/direction to food sources, motivating study of possible dances or signals.

Environment, Shankar IAS Acedemy .(ed 10th) > Chapter 6: Environmental Issues > Malnutrition > p. 120
Strength: 2/5
“Beekeepers collect (steal) bees' honey so humans can consume it, they are taking away the insects' food. They replace it with high-fructose corn syrup, leaving the bees malnourished and weakening their immune systems. Researchers have identified some specific nutrients that bees need, get from honey, and don't get from corn syrup. When honeybees collect nectar from flowers, they also gather pollen and a substance called propolis, which they use to make waxy honeycombs. The pollen and propolis are loaded with three types of compounds that can help the bees detoxify their cells and protect themselves from pesticides and microbes.”
Why relevant

Explains that when honeybees collect nectar they also gather pollen and propolis, showing foraging is a key collective activity involving multiple resources.

How to extend

This supports asking how foragers inform nestmates about profitable multi-resource locations (suggesting the need to communicate where resources are), which could lead one to check for behaviors that convey direction/distance.
