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: β€”  Β·  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.

β€œtranslocate 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

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.

Strength: 3/5
β€œApiculture 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
β€œA 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 dronesβ€”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
β€œBeekeepers 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.

Strength: 5/5
β€œBees are one of a myriad of other animals, including birds, bats, beetles, and butterflies, called pollinators. Pollinators transfer pollen and seeds from one flower to another, fertilizing the plant so it can grow and produce food. Cross-pollination helps at least 30 percent of the world's crops and go percent of our wild-plants to thrive. Without bees to spread seeds, many plants - including food crops - would die off. Bees are not summertime nuisance, they are small and hard-working insects actually make it possible for many of your favorite foods to reach your table. From apples to almonds to the pumpkin in our pumpkin pies, we have bees to thank.”
Why relevant

Lists bees alongside butterflies as pollinators; bees are a well-known insect group that use a waggle dance to communicate food locations.

How to extend

A student could note that because closely associated pollinators (bees) use dance communication, they should check behavioural literature or observations to see if butterflies show comparable signalling.

Why relevant

Gives an explicit example of a species (the Bengal Florican) using a dance as a communicative/advertising behaviour (mating/territory).

How to extend

One can generalise that 'dance' can be used for communication in animals, so test whether butterflies use dance specifically for foraging by seeking observational studies or analogies in insects.

Why relevant

Explains that organisms compete for common resources like food, providing a general motivation for animals to evolve signals that direct conspecifics to resources.

How to extend

A student could infer that if butterflies benefit from informing conspecifics about rich food, they might evolve signalling β€” prompting targeted searches for such foraging communication in butterflies.

β€œSome species have symbiotic relationships, an arrangement that mutually benefts and sustains each organism. For example, lichen (pronounced "liken") is made up of algae and fungi living together. Te algae is the producer and food source, and the fungus provides structure and physical support. Teir mutually benefcial relationship (mutualism) allows the two to occupy a niche in which neither could survive alone. An ecological niche consists of: β€’ (i) Habitat– where the species live.β€’ (ii) Food niche what a species eats and decomposes and what species it competes with.β€’ (iii) Reproductive niche how and when it reproduces.β€’ (iv) Physical and chemical niche temperature, moisture, and landform.β€’ (v) Geo-ecological niche– topography, terrain, slope, and soils etc.”
Why relevant

Defines 'food niche' as part of an ecological niche, tying species behaviour to how and where they obtain food.

How to extend

Using this, a student could investigate whether butterflies’ food-niche behaviours include social communication (e.g., dance) by comparing with known niche-related behaviours in other insects.

Why relevant

Gives a clear example of an animal (the Bengal florican) using a repeated aerial 'dance' as a communication/advertising behaviour.

How to extend

A student could use this pattern (dances used as communication in animals) and then check whether the waggle dance is specific to certain taxa (e.g., birds vs insects) and whether dragonflies show similar social signalling.

Why relevant

Lists dragonflies alongside bees and butterflies in the same ecological context and notes dragonflies are predators of other insects.

How to extend

Combine this with knowledge that the waggle dance is associated with social foragers (bees) to test whether a predatory, often solitary insect like a dragonfly would benefit from or exhibit such recruitment signalling.

Why relevant

Mentions worker bees and colony-level phenomena (workers failing to return), indicating bees have colony organisation and worker behaviour that affect foraging and communication.

How to extend

Knowing bees have sophisticated foraging/colony behaviours, a student might compare documented bee communication (e.g., waggle dance from outside sources) with wasp social/foraging systems to judge plausibility.

Why relevant

Shows organisms (plants) use chemical signalling to inform others of resource-related threats β€” a general pattern that non-vocal communication exists across life forms.

How to extend

A student might generalise that many taxa have non-verbal signals for resource/location/alerting and therefore check whether wasps have any non-vocal foraging signals comparable to bee dances.

Pattern takeaway: UPSC targets 'Anthropomorphic' traits in animalsβ€”behaviors that resemble human skills like farming (fungus-growing ants), dancing (bees), or tool use (orangutans). If an animal has a 'culture' or 'language,' it is high-priority.
How you should have studied
  1. [THE VERDICT]: Sitter for Science backgrounds; Moderate for others. This is a classic biology fact, not obscure trivia.
  2. [THE CONCEPTUAL TRIGGER]: 'Eusocial Insects' and 'Animal Communication' within the Biodiversity module. Specifically, how colony-based insects (Ants, Bees, Termites) coordinate foraging.
  3. [THE HORIZONTAL EXPANSION]: 1. **Round Dance**: Used by bees for food <50-100m away (no direction info). 2. **Solar Azimuth**: The angle of the waggle run relative to gravity matches the angle of food relative to the sun. 3. **Stridulation**: How crickets/grasshoppers produce sound (rubbing legs/wings). 4. **Trophallaxis**: Mouth-to-mouth food transfer in ants/bees to share chemical signals. 5. **Stigmergy**: Indirect coordination in termites (building complex mounds without a blueprint).
  4. [THE STRATEGIC METACOGNITION]: When studying 'Keystone Species' like Bees, ask *functional* questions: How do they navigate? How do they communicate? UPSC loves 'superlative' behaviors (e.g., the most complex dance, the longest migration, the unique tool usage).

πŸ”— Anchor: "Do dragonflies perform a waggle dance to communicate the direction and distance ..."
πŸŒ‘ The Hidden Trap

The 'Round Dance'. While the Waggle dance (distance >100m) encodes direction, the Round dance (distance <50m) only indicates 'food is near' without direction. Another sibling fact: 'Stridulation' is the term for sound production in crickets, often confused with vocalization.

⚑ Elimination Cheat Code

Apply the 'Social vs. Solitary' filter. The question mentions communicating to 'others of their kin' to fetch food. This requires a 'Central Place Forager' (one who returns to a hive). Butterflies and Dragonflies are largely solitary foragers; they don't have a hive to report back to. This leaves Wasps and Honeybees. Honeybees are the 'poster child' of complex social behavior in NCERTs.

πŸ”— Mains Connection

Connects to GS-3 Agriculture (Food Security): 70% of global crops depend on pollination. The decline of this 'dance' (due to pesticides/CCD) directly impacts the 'Doubling Farmers Income' goal by reducing crop yields.
