I have always been interested in life of butterflies.
I spend a lot of time finding some interesting materials about them: stories, photos, articles and etc. 
I have a big collection of post-cards, posters, calendars, stamps with different kinds of butterlies.
There is very little that I don't know about their life and habbits.
It's a rather uncommon hobby.
I think it's an exciting pastime.
