Female eastern tiger swallowtail shows blue along wings. When looking at a yellow tiger swallowtail, if it shows these same blue markings on the wings, it is probably also female. The male eastern tiger swallowtails are always predominantly yellow with black showing mostly as the tiger stripes. And the male seldom has much blue on its wings. There appeared to be more females than males on World Peace Wetland Prairie last week.
