The Baltimore checkerspot butterfly (Euphydryas phaeton) is a striking and easily recognizable species native to Massachusetts. Known for their striking wing patterns, often featuring contrasting colors and, as the name suggests, checkered or spotted markings. While there are several species within the genus, they all share similar characteristics and behaviors.
Baltimore checkerspot butterflies play a significant role in pollination, particularly in garden ecosystems. As they flit from flower to flower in search of nectar, they inadvertently transfer pollen grains from one plant to another, facilitating the process of fertilization and seed production. This act of pollination is essential for the reproduction of many flowering plants, including those commonly found in gardens.
The Baltimore checkerspot butterfly has a wingspan of about 1.5 to 2.5 inches and are predominantly black with bright orange or red markings, including distinctive rows of white or yellow spots. The undersides of the wings are usually a darker color with lighter markings. These butterflies have a characteristic checkered pattern on their wings, which gives them their name.

In addition to their pollination services, checkerspot butterflies also contribute to the overall biodiversity and ecological balance of garden environments. They serve as indicators of ecosystem health, with their presence often signaling a thriving and diverse habitat. By attracting these butterflies to gardens through the cultivation of their preferred nectar plants, gardeners can enhance the resilience and vitality of their ecosystems.
Plant native host plants: Baltimore checkerspot butterfly caterpillars feed on specific native plants such as turtlehead (Chelone glabra) and white turtlehead (Chelone obliqua).
Provide nectar-rich flowers: Adult Baltimore checkerspot butterflies feed on the nectar of various flowers. Planting a diverse array of nectar-rich flowers such as milkweed, coneflowers, asters, and butterfly weed can attract adult butterflies to your garden.
Create a butterfly-friendly habitat: Provide sheltered areas, such as shrubs and tall grasses, where butterflies can seek refuge from harsh weather conditions and predators.
Avoid pesticides: Pesticides can harm butterflies and other beneficial insects. Opt for natural pest control methods and avoid using chemical pesticides in your garden.
Provide a water source: Butterflies need water for hydration. Place shallow dishes filled with water or create a small shallow pond or birdbath with rocks for butterflies to perch on while drinking.
Creating butterfly-friendly habitats in gardens not only benefits checkerspot butterflies but also supports other pollinators and wildlife species. Planting a variety of nectar-rich flowers, providing sheltered resting spots, and avoiding the use of pesticides are all ways to encourage these beautiful insects to visit and thrive in garden spaces. In return, they help to ensure the continued beauty and productivity of garden landscapes through their essential role as pollinators.
