### Instruction: From the given passage, write down some interesting points on butterflies
### Input: Butterflies (Rhopalocera) are insects that have large, often brightly coloured wings, and a conspicuous, fluttering flight. The group comprises the superfamilies Hedyloidea (moth-butterflies in the Americas) and Papilionoidea. Butterfly fossils date to the Paleocene, about 56 million years ago.

Butterflies have a four-stage life cycle, as like most insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, and after its wings have expanded and dried, it flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take several years to pass through their entire life cycle.
### Response: 1. Butterflies (Rhopalocera) are insects that have large, frequently vividly coloured wings and prominent, fluttering flight patterns.
2. The superfamilies Hedyloidea (moth-butterflies in the Americas) and Papilionoidea make up the group. 
3. Around 56 million years ago, during the Paleocene, butterflies first appeared.
4. Butterflies go through a full metamorphosis, like other insects, and have a four-stage life cycle.
5. Winged adults lay their eggs on the food plant that their caterpillar-like larvae will consume.
6. The caterpillars mature, sometimes very quickly, then pupate in chrysalises once completely grown.
7. After transformation is complete, the adult insect crawls out of the pupal skin and dries its wings before taking flight.
8. Some butterflies, especially those that live in tropical climates, have multiple generations every year, while others only have one. Some butterflies that live in frigid climates may take several years to complete their whole life cycle.
