Mourning Cloak Butterfly Markings
The appearance of a mourning cloak butterfly typically signals the start for spring for many people. Look for dark maroon wings, yellow speckling on the leading edge and a yellow band on the outer portion of the wing. Also look for blue dots that run along the yellow band. Their wingspan is 2 1/4 to 4 inches.
“I captured this shot of a mourning cloak (above) getting nectar from a coneflower in my garden. I have a fairly large yard with lots of flowers and trees. The mourning cloaks seem to like an area with dead leaves, tree stumps and branch piles,” says Brenda Doherty of Ariss, Ontario.
Where to Find a Mourning Cloak Butterfly
You can find this big, distinctive butterfly throughout North America—and almost throughout the year. Mourning cloaks can spotted anywhere from northern Canada all the way to Guatemala. They’re also seen in Europe and Asia. A huge plus for butterfly lovers is that mourning cloaks frequent a variety of locations, including banks of streams, woods, parks and suburbs.
While most butterflies pass the winter in the caterpillar, pupa or egg stage, the mourning cloak hibernates as an adult. This means it could come out on warm winter days. Even in the north, it will fly during February thaws, and it makes a stunning sight as it glides through snowy woods.
