<human>:  My daughter is researching about insects for her science assignment. Can you help her with finding interesting facts about butterflies?
<bot>: 
1. Butterflies go through a complete metamorphosis, meaning they go through four stages—egg, larva (caterpillar), pupa (chrysalis), and adult.
2. Butterflies taste with their feet! They have taste receptors on their feet which they use to test whether a leaf or flower has the right food for them.
3. There are over 20,000 species of butterflies in the world and they live on every continent except Antarctica.
4. The top recorded flight speed of a butterfly is 12 miles per hour.
5. Many butterflies migrate long distances, some even crossing the Gulf of Mexico.
6. Female butterflies are generally larger than the males.
7. Butterflies help pollinate flowers and fruits as they drink nectar from the flowers.
8. Butterfly wings have tiny scales made of chitin which give it its unique color.
