๐ Q.5 IAS Prelims 2023 โ Environment & Ecology (Waggle Dance Communication)๐งท Authentic Classroom Explanation by IAS Monk
๐ The Question
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?
(a) Butterflies
(b) Dragonflies
(c) Honeybees
(d) Wasps
โ Correct Answer: (c) Honeybees
๐งโ๐ซ Classroom Explanation
The waggle dance is a sophisticated symbolic communication system used exclusively by worker honeybees to inform other members of the hive about:
- Direction of food source
- Distance of food source
๐ฌ This behaviour was decoded by Karl von Frisch, for which he later received the Nobel Prize.
How the waggle dance works:
- ๐งญ Direction:
- Vertical upward movement โ food source is towards the Sun
- Angle of waggle relative to vertical โ angle relative to Sunโs position
- ๐ Distance:
- Duration of the waggle phase indicates how far the food source is
No other listed insects possess such a precise, encoded spatial language.
โก Curiosity Raiser
Honeybees can communicate kilometre-level distances without maps, GPS, or sound.
What does that say about collective intelligence in nature?
๐ Enrich Notes (UPSC Edge)
- Waggle dance is an example of ethology (study of animal behaviour)
- It is:
- Species-specific
- Learned + instinctive
- Frequently asked in UPSC under:
- Animal behaviour
- Ecology communication
- Nobel-linked discoveries
๐ซ Butterflies, dragonflies, and wasps do not perform waggle dances.
