Checkerspot Butterfly: All You Need to Know in a Nutshell

The Checkerspot butterfly is a fascinating species that has captured the attention of nature enthusiasts and conservationists alike. Known for their striking patterns and vibrant colors, these captivating insects are a beautiful sight to behold. There are multiple subspecies of Checkerspot butterflies, such as Taylor’s Checkerspot and the Baltimore Checkerspot, each displaying unique features.

Taylor’s Checkerspot, for instance, has a wingspan of around 5.7 centimeters and displays a checkered pattern of orange, black, and cream colors on its wings source. On the other hand, the Baltimore Checkerspot is the official insect of Maryland and has a wingspan of roughly 2.5 inches source. Both these subspecies belong to the family Nymphalidae, also known as brushfooted butterflies. Their reduced front legs give the appearance of having four legs instead of six.

Checkerspot butterflies face many challenges, including loss of habitat and decline in population numbers, particularly for the Taylor’s Checkerspot subspecies source. Conservation efforts are in place to help protect and preserve these butterflies and their natural habitats. In learning about the Checkerspot butterfly, we can understand the importance of these incredible creatures and their role in maintaining a balanced ecosystem.

Habitats and Distribution

North America

The Checkerspot butterfly is found in various regions of North America, inhabiting grasslands and prairies.

• Habitat: Grasslands and prairies
• Regions: Pacific Northwest, East Coast, and Southwest

In Oregon, the Taylor’s Checkerspot butterfly is found primarily in native prairies of the Pacific Northwest region ¹.

• Limited to 2 populations
• Endemic to Pacific Northwest

Washington

Similarly, Washington is home to a small scattering of Taylor’s Checkerspot butterfly populations ².

• Restricted to 8 populations
• Dependent on prairie and grassland habitats

British Columbia

Only a single population of the Taylor’s Checkerspot butterfly currently exists in British Columbia ².

• One known population
• Pacific Northwest endemic

East Coast

On the East Coast, the Baltimore Checkerspot butterfly is the state insect of Maryland ³.

Reproduction and Life Cycle

Eggs

The Taylor’s Checkerspot butterfly begins its life as an egg. Female butterflies lay their eggs on a leaf, either singly or in clusters ¹.

Caterpillars

Upon hatching, the Checkerspot caterpillars, also known as larvae, come out. These caterpillars have a primary function: to eat and grow ². Some characteristics of Checkerspot caterpillars include:

• Munching on leaves from host plants
• Going through multiple growth stages, called instars

Chrysalis

After growing throughout their larval stage, the Checkerspot caterpillars transition into the pupal stage. During this time, they form a protective casing around themselves known as a chrysalis ³. Inside the chrysalis:

• The caterpillar body transforms
• New body structures develop

Adult Butterfly

Once metamorphosis is complete, the adult Checkerspot butterfly emerges from the chrysalis ⁴. The adult butterfly has a wingspan of about 2.25 inches and a life span of approximately 30 days ⁵. Adult butterflies have several key features:

• Notable wing patterns
• Mating and reproducing during their peak flight period

Diet and Host Plants

Nectar Plants

Checkerspot butterflies depend on nectar plants as their primary food source. Nectar plants provide energy to adult butterflies, enabling them to fly, mate, and lay eggs. Some favorite nectar plants for checkerspot butterflies include:

• Castilleja hispida
• Plantains
• Sea blush

It’s essential to include native plants in a butterfly garden to support the checkerspot species. For better results, use a variety of native plants to attract a diverse range of butterflies.

Host Plants

In addition to nectar plants, host plants play a crucial role in checkerspot butterfly reproduction. Adult females tend to lay their eggs on host plants that provide food for the emerging caterpillars. Examples of host plants for checkerspot butterfly larvae include:

• Penstemon
• Orthocarpus
• Collinsia

Pros of using native plants:

• Attract local butterfly species
• Support the life cycle of butterflies

Cons of using native plants:

• May not be readily available

In conclusion, to support the checkerspot butterfly species, it is crucial to incorporate both nectar and host plants in a garden. Native plants are particularly important, as they help sustain the butterfly’s life cycle and ensure their survival.

Conservation and Threats

Endangered Species

The Taylor’s checkerspot butterfly is endemic to the Pacific Northwest and currently listed as an endangered species. It now only survives at a small handful of sites due to habitat loss and other threats.

Key Features of Taylor’s Checkerspot Butterfly:

• Endemic to the Pacific Northwest
• Endangered species
• Restricted to a small number of sites

Habitat Loss

Habitat loss has played a significant role in the decline of checkerspot butterflies. For instance, the decline of Taylor’s checkerspot is primarily due to the loss of native prairies in the Pacific Northwest.

Examples of habitat loss:

• Native prairie loss in the Pacific Northwest
• Urban development encroaching on habitats

Climate Change

Climate change can also pose a threat to checkerspot butterflies by altering their habitat and endangering their survival. For example, changes in temperature and precipitation patterns can affect the distribution and abundance of their host plants, putting the species at risk.

Gardening for Checkerspots

Many people admire checkerspot butterflies and want to attract them to their gardens. Here are some tips for creating a checkerspot-friendly garden:

• Plant native host plants: Checkerspot caterpillars rely on specific host plants for food. Planting these in your garden can attract checkerspots.
• Provide nectar sources: Adult checkerspot butterflies feed on nectar from flowers. Plant a variety of nectar-rich flowers to cater to their needs.
• Create shelter: Butterflies need shelter from predators and adverse weather. Provide some shrubs and tall grasses where they can take cover.

Some key features of checkerspot butterflies include:

• Wingspan: Medium-sized, with a wingspan of approximately 2.25 to 2.5 inches.
