Identifying the Mourning Cloak Butterfly: A Step-by-Step Guide

Let’s break down the identification process into easy-to-follow steps. We’ll focus on the key characteristics that set the Mourning Cloak apart from other butterflies.

1. Wing Color and Markings

The most obvious feature of the Mourning Cloak is its wing color. Here’s what to look for:

Base Color: The wings are primarily a dark chocolate brown or a deep maroon color.
Yellow Border: A broad, creamy yellow or light golden band runs along the outer edge of both the forewings and hindwings. This is a key identifier!
Blue Spots: A row of iridescent blue spots is located just inside the yellow border. These spots add a beautiful contrast to the dark wings.

2. Size and Shape

Mourning Cloaks are medium-sized butterflies. Knowing their approximate size helps narrow down your identification.

Wingspan: They typically have a wingspan of about 2.5 to 4 inches (6.3 to 10 cm).
Wing Shape: The wings are relatively broad and rounded, not sharply pointed like some other butterfly species.

3. Body Characteristics

Pay attention to the butterfly’s body as well.

Body Color: The body is usually dark brown or black, matching the base color of the wings.
Antennae: They have clubbed antennae, which are common among butterflies.

4. Behavior and Habitat

Observing the butterfly’s behavior and knowing its preferred habitat can provide additional clues.

Early Emergence: Mourning Cloaks are among the first butterflies to emerge in the spring, often seen as early as March or even late February in warmer climates.
Habitat: They are found in a wide variety of habitats, including forests, woodlands, parks, gardens, and even urban areas. They prefer areas near trees, especially willows, elms, and birches, which are host plants for their caterpillars.
Sunbathing: Mourning Cloaks often bask in the sun with their wings open to absorb warmth.

Distinguishing Mourning Cloaks from Similar Butterflies

While the Mourning Cloak is fairly distinctive, there are a few other butterflies that might cause confusion. Here’s how to tell them apart:

1. Compton Tortoiseshell (Nymphalis vaualbum)

The Compton Tortoiseshell is similar in size and shape to the Mourning Cloak, but there are key differences:

Wing Pattern: The Compton Tortoiseshell has orange and brown markings on its wings, unlike the Mourning Cloak’s solid dark brown.
White Mark: Look for a small, distinct white “C” mark on the underside of the hindwing of the Compton Tortoiseshell. The Mourning Cloak lacks this mark.

2. California Tortoiseshell (Nymphalis californica)

This butterfly is found primarily in the western United States. Here’s how to differentiate it:

Orange Coloration: The California Tortoiseshell is primarily orange with dark brown and black markings.
Lack of Blue Spots: It doesn’t have the row of blue spots found on the Mourning Cloak.

3. Question Mark (Polygonia interrogationis)

The Question Mark butterfly can look similar at first glance because of its dark color, but:

Wing Shape: The Question Mark has jagged wing edges, unlike the smoother, rounded wings of the Mourning Cloak.
Question Mark: It has a distinctive silver “question mark” on the underside of its hindwing.

Mourning Cloak Butterfly: A Detailed Look

Let’s delve deeper into the fascinating life and characteristics of the Mourning Cloak butterfly.

Physical Attributes

The Mourning Cloak (Nymphalis antiopa) is a butterfly admired for its unique and elegant appearance. Here’s a closer examination of its physical traits:

Wingspan: Generally ranges from 2.5 to 4 inches, making it a medium-sized butterfly.
Wing Coloration: The base color is a dark, rich chocolate brown, often appearing almost black.
Yellow Border: A prominent, pale-yellow border lines the edges of both the forewings and hindwings. This border can sometimes appear cream-colored or golden.
Blue Spots: A series of iridescent blue spots are situated just inside the yellow border, adding a striking contrast.
Underside: The underside of the wings is a dark grayish-brown with lighter striations, providing excellent camouflage when the butterfly is at rest.
Body: The body is typically dark brown or black, blending well with the wing colors.
Antennae: Possesses clubbed antennae, common to most butterflies, which they use for sensing their environment.

Life Cycle

The life cycle of the Mourning Cloak is a fascinating transformation from egg to adult. Here’s a detailed look at each stage:

Egg Stage:
- The female Mourning Cloak lays her eggs in clusters around twigs of host plants, such as willow, elm, birch, and hackberry trees.
- The eggs are barrel-shaped and ribbed, often starting as pale yellow and darkening as they mature.
Larva (Caterpillar) Stage:
- Once hatched, the caterpillars are gregarious, meaning they feed and live together in groups, especially during their early instars.
- The caterpillars are black with white speckles and have rows of red spots along their backs. They also have branched spines, giving them a somewhat prickly appearance.
- As they grow, they molt several times, each stage known as an instar.
Pupa (Chrysalis) Stage:
- When the caterpillar is ready to pupate, it hangs upside down from a twig or leaf and forms a chrysalis.
- The chrysalis is typically gray or brown, camouflaged to blend in with its surroundings. It has a spiky appearance.
- Inside the chrysalis, the caterpillar undergoes metamorphosis, transforming into a butterfly.
Adult Stage:
- After about two to three weeks, the adult butterfly emerges from the chrysalis.
- The newly emerged butterfly unfolds its wings and allows them to dry and harden before taking its first flight.
- Adult Mourning Cloaks are known for their longevity, with some individuals living for up to 10-11 months. They overwinter as adults, often finding shelter under loose bark or in tree cavities.
