Day 140: Butterfly or Moth?

I went to my backyard again today and saw this white butterfly... or is it a moth? lol Man, I fail at recognizing things! This was pretty sudden though, since I actually planned to photograph something else but then I saw this little butterfly flying around. After I managed to put it on my finger, I accidentally squished (barely) one of it's arms. It became frightened and flew away. *sigh* I had a good idea on the composition but then I had to be too excited and scared it away :( Bleeeeh, whatever. Maybe next time.
