The Sulfur Butterfly

I got these pictures yesterday morning. As I was about to drive off my car, I saw a bright yellow butterfly landed in the flower. I quickily went back to the house and took my camera out. Somehow I felt that this butterfly is doing some posing for me, which I could take my time to take photos of it.

Here's what my Aunt Doreen told me about this butterfly.

"The butterfly is commonly known as the Sulfur Butterfly, in the family Pieridae.... as it loves to feed at salt or sulfur pools. Used to be very common on the way to Luasong in the old days before logging destroyed a lot of their habitat. The road used to be covered with them feeding on animal droppings or drinking off running pools of fresh mountain flows. Gone are those days!"
