Your outdoor area will remain lively throughout the year if it appeals to cardinals. The northern cardinal is a distinctive non-migratory songbird species, which means you can enjoy spotting the vibrant red-plumaged males either when they’re attempting to attract a partner or simply moving about searching for sustenance. Their presence guarantees a delightful spectacle.

These delightful birds search for insects while tending to their offspring during the warmer seasons. If you wish to draw them in spring and summer, ensure that caterpillars are abundant.
After building their nests in late winter, Cardinals look for nutrient-rich caterpillars. For up to two months following hatching, they provide caterpillars and other insects to their offspring. To guarantee sustenance for both the fledglings and their parents hunting food, consider planting herbs that serve as hosts for these larvae-eating creatures. Dill (Anethum graveolens) and milkweed (Asclepias syriaca) are examples of such host plants where adult butterflies deposit their eggs; consequently, the caterpillars thrive on them.

Herbs and Flowers Attract Caterpillars to Your Garden
Certain caterpillars consume the foliage of just one or a couple specific plant varieties; however, fortunately for us, cardinals have a more varied appetite when it comes to selecting caterpillars as food. As these birds mature within their nests, they feed on numerous kinds of larval insects and caterpillars from different butterflies like the Eastern black swallowtail, monarch, and silvery checkerspot species.
Multiple herbs support the growth of Eastern black swallowtail butterfly larvae. Among these, dill—a versatile culinary herb thriving in sunny conditions with somewhat acidic earth—is notably advantageous.
a widely loved herb for attracting butterflies to your garden
The ideal environment for these creatures spans USDA hardiness zones 2 to 11. They primarily consume curly and flat-leaf types of parsley (Petroselinum crispum), which thrive in damp soil with partial shade, as well as fennel (Foeniculum vulgare) — an herb known for its sweet, licorice-like flavor that flourishes within USDA hardiness zones 4 to 9. During this period, they’ll feed on the plants—and may become prey for cardinals—for roughly one month.
Monarch butterfly larvae solely consume common milkweed, which is a long-lived plant blooming during summertime. This species thrives best in sunny locations with well-drained earth; however, it also has the ability to survive in inferior or drier conditions and prospers within USDA resilience regions from 3 to 9.
An alternative choice is to cultivate coneflowers (Echinacea angustifolia). These perennials thrive even in rocky or nutrient-poor soils and draw silvery checkerspot caterpillars. They are typically initiated from seeds indoors or planted outdoors directly into seedbeds during spring or summer months.
Spotting Caterpillars And Cardinals
After your plants have taken root, keep an eye out for indications that caterpillars might be thriving closeby. For dill, parsley, and fennel, spotting small yellow eggs on the foliage suggests success; within roughly seven days, these should yield baby black caterpillars. Mature Eastern black swallowtails display vivid green coloring adorned with black-and-yellow markings.
Should you cultivate milkweed, stay vigilant during February and March—the months when monarch butterflies deposit minuscule cream-hued eggs. As they develop into larvae, expect them to appear pale grey or light green, featuring patterns of yellow, black, and white bands. When tending coneflowers, search for the distinctive dark-haired larvae of the silvery checkerspot butterfly—these critters often gather en masse upon leaf surfaces following hatching from grouped clusters of eggs.
Along with planting the flowers and herbs that these caterpillars eat, think about whether your vegetation supports cardinal birds’ nesting behaviors. Do you have nearby bushes, trees, or thick shrubbery? These elements offer excellent nesting spots that could
draw cardinals into your garden
There will be several signs indicating that your planting endeavors are drawing in cardinals. These birds construct small, bowl-like nests using roots, grasses, and various natural elements. Nests might sit as little as 3 feet off the ground, though they often require a sharp gaze to detect. While a female cardinal adorned with red markings against her olive-gray plumage or a young brown cardinal isn’t quite as vibrant as their bright-red male counterparts, spotting one could suggest a nearby nest just within reach of flying about.
