Why do flies rub their legs together?

Show answer & explanation

Answer: To clean their sensors

It's a mating dance — Wrong. Leg rubbing isn't part of fly courtship. They have different behaviors for attracting mates.

To clean their sensors ✓ — Correct! Flies taste and smell with sensors on their feet! Rubbing removes dirt and food particles so these sensors work properly. Clean feet help flies find their next meal.

They're showing happiness — Wrong. Insects don't express emotions like happiness. The rubbing is purely functional—keeping sensory organs clean.
