When we arrived home, I saw this on the front window. It is big and the color is so pretty. This moth is called Actias luna or Luna Moth which has a distinctive lime-green color. It is really big in fact, it has a wingspan of up to 4.5 inches that is why, it is one of the largest moths around.
I just take a picture and leave it there. They have the right to live you know so; I let the moth hang in there.
