Butterfly

A couple days ago I ran into a butterfly. Well not ran into but saw one on the side of the road.
I was very thrilled to see butterflies because I haven't seen them around in ages. Strangly yesterday I saw a website where you could report a butterfly spotting.
So they coud keep track of the animals living around us.
I loved the idea, I wanted to join them but then I realize I don't know anything about butterflies.
This one was a black and white one an not really large, but not really small either.
So I guess I am not of much help to the website.. bummer...
