Monarch Butterflies in West Virginia: identification guide and best places to start

Monarchs have bright orange wings with thick black veins and a double row of white spots along the trailing edge. The wingspan is about 3.5 to 4 inches. Look for the distinctive black border with two rows of white dots. The similar viceroy butterfly has a single row of white spots and an extra black band across the hindwing. In West Virginia, you may also see the queen butterfly, but that species is darker and smaller.

The fall migration peaks in September and October. West Virginia lies right along the eastern flyway, so you can expect large numbers moving southwest toward Mexico. Spring migration (April to June) is less concentrated but still present. Warm, sunny days with light winds are best for spotting them. Cold fronts often push them into sheltered valleys, making those days productive.

Your best odds are in open fields with abundant goldenrod, asters, and milkweed. The Ohio River valley from Wheeling to Huntington is a major migration corridor. Also try the high meadows in the Monongahela National Forest, especially along the Greenbrier River Trail. Backyard gardens with native nectar plants can also attract them.

Adults feed on nectar from flowers like goldenrod, joe-pye weed, and purple coneflower. Caterpillars eat only milkweed. In West Virginia, common milkweed and swamp milkweed are the host plants. If you want to attract monarchs, plant a mix of late-blooming natives. For a deeper look at their life cycle, visit our monarch butterfly guide.

Males have a small black scent patch on each hindwing, visible as a dark spot near the base. Females lack this patch and have thicker, darker veins overall. In flight, males tend to patrol for mates while females are more focused on finding milkweed. Use these cues for quick field ID.
