This is a Gray Comma butterfly. I found it in our yard and, even though it is apparently quite wide spread here in the North Woods, it is the first one I have seen. Butterflies in our area have to find a way to cope with our winters. Each species makes it through the winter in one of the four stages of their life (egg, caterpillar, pupa, or adult). The Gray Comma overwinters as an adult, often finding shelter in wood piles or outbuildings.
