The official insect of the state of Maryland, the black and orange Baltimore checkerspot butterfly graces the second butterfly stamp.
Like the Baltimore oriole, this colorful butterfly is ... a checkered pattern on black wings. The butterfly has an unusual life cycle. It spends the winter hibernating as a caterpillar, rolled up in a fallenleaf which it uses a sleeping bag.
