Fun facts
It is the official state insect of Maryland, chosen in 1973.
Most butterflies spend the winter as an egg or a pupa, but this one spends it as a caterpillar hiding in dead leaves on the ground.
Before winter, the caterpillars spin a little web on a plant, stop eating and rest inside it for months.
In Maryland it has become so rare that it is listed as endangered.
