Latin Name

Nymphalis antiopa


This butterfly is found in North America, Europe, and Asia. It has a broad range, from the cold arctic regions to the warmer parts of North America.


Caterpillar: Spiky black body covered with white speckles and a row of bright red spots running down the back. Butterfly: Dark maroon wings with a ragged yellow border and a row of iridescent blue spots.


Wingspan ranges between 2.25 to 4 inches. The caterpillar can grow up to 2 inches in length.


Various environments, from woodlands and forests to parks and even suburban areas.


Caterpillar: Feeds primarily on the leaves of trees like willow, elm, poplar, and hackberry. Butterfly: Prefers tree sap, especially oak. It also consumes rotting fruit and, less commonly, flower nectar.


Egg → caterpillar (larva) → chrysalis (pupa) → adult butterfly. One unique trait of the Mourning Cloak is that adults overwinter, emerging in spring to mate.


Mourning Cloaks, like other butterflies, primarily use visual and chemical cues for communication. Males often set up territories and will perch on tree trunks or sunlit areas on the ground, driving away other intruding males.

Defense Mechanisms

Caterpillar: The spiky appearance and bright colors serve as a warning to potential predators of their unpleasant taste. Butterfly: Its dark wing coloration offers excellent camouflage against tree trunks, especially when overwintering. The bright edges may also serve as a warning or distraction.

Ecological Importance

They are essential for pollination, albeit less reliant on flowers. Their larvae are also a food source for various predators, thereby contributing to the food chain.

Conservation Status

The Mourning Cloak is not considered endangered and is common across its vast range.
