Which is NOT a social animal?

Step 1: Analyze the question The question asks which animal is NOT a social animal. We need to know what "social" means in biology.

Step 2: Explain the concept Social animals live in organized groups or colonies. They show cooperation, division of labour, and often a caste system or hierarchy.

• Social insects (eusocial): ants, bees, termites, and some wasps. They live in colonies with queens, workers, soldiers, and so on.
• Social mammals: wolves live in packs with a clear hierarchy (alpha leader) and hunt cooperatively.
• Solitary animals: they live and work mostly alone, only meeting to mate.

Step 3: Go through the options

• A. Ant: Social. Lives in colonies with queen, workers, and soldiers.
• B. Bee: Social. Lives in hives with a queen, workers, and drones.
• C. Butterfly: Not social. Butterflies live individually and do not form organized colonies with division of labour. They may gather in groups to feed or migrate, but this is not true social organization.
• D. Termite: Social. Lives in colonies with king, queen, workers, and soldiers.
• E. Wolf: Social. Lives and hunts in packs.

Step 4: Answer The butterfly is the animal that is not social, so the answer is C.

Tip: For "social animal" questions, remember the ABT trio: Ants, Bees, Termites. These are the classic social insects with castes. Butterflies, grasshoppers, and beetles are mostly solitary. Look for words like "colony," "caste," and "division of labour" as signs of social living.
