Specifically, the American Painted Lady butterfly!
You might see this beauty already. Painted Ladies migrate north in the spring from their wintering grounds in the Southwest. It’s one of the most widespread butterflies North America, so definitely look for Painted Ladies this summer. And you may need to look twice, because the underside of the wings is patterned differently from the topside.
Pretty cool, huh? Their populations vary from year to year, and scientists don’t know why. They do not migrate back in the fall, so die with the first frosts.
