need help for raising butterflies

[Pedro]

	hi, my name is Pedro, i'm 17 and live in Brazil. Last week a
butterfly was landed on my room's wall for a long time. after she went
away i noticed that she had left 5 little yellow eggs on my wall. I'm
quite interested in taking care of these specimens till they become
actual butterflies, but i've no idea how to do it. can someone please
help me? i'll be very grateful and promise to send pictures of their
development!
thanks
Pedro
