Can you tell butterflies from moths?

we cant tell butterfly as moth
as i know but moths are attracted towards flame but not the butterfly
it is also beautiful

We dont have moths here. Now we dont even have butterflies. You know when I was in primary school, our classes were on the second floor of the building. During November December season "we call it Sri Pada Season" there are huge flocks of butterflies specially small yellow ones who fly passing our school. We believe they go to this mountain "Sri Pada" which is known as Adam's Peak where Lord Buddha has placed his right foot print to offer themselves. I dont know how far it is true. But there were lots of them during that time. Now we cant find any thanks to pesticides and pollution.
