Monarch Butterflies in Montana: identification guide and where to start looking

1. What types of monarch butterflies live in Montana?

In Montana, you will only find one species of monarch butterfly: *Danaus plexippus plexippus*, the North American monarch. There are no other subspecies or distinct types in the state. Some people mistakenly think viceroys or queens are different types, but they are separate species. The monarch in Montana is the same orange-and-black butterfly seen across the continent.

2. How can you identify a monarch butterfly in Montana?

Look for bright orange wings with thick black veins and a black border dotted with white spots. Monarchs have a wingspan of 3.5 to 4 inches. Males have two black spots on their hindwings (scent glands), while females lack these spots. They fly with a slow, floating pattern. The underside of the wings is a paler orange with similar markings, often seen when they rest with wings closed.

3. What lookalikes are often confused with monarchs in Montana?

The viceroy butterfly is the most common lookalike. Viceroys are smaller (wingspan about 2.5 to 3 inches) and have a black horizontal line across the hindwing that monarchs lack. Queens, another mimic, are darker orange with less distinct black veins and no white spots on the black borders. Learning these differences is key to accurate identification.

4. Where in Montana are monarchs most commonly spotted?

Monarchs are most often seen in the eastern two-thirds of Montana, especially in prairie habitats with milkweed. Good spots include the Charles M. Russell National Wildlife Refuge, the Missouri River Breaks, and along the Yellowstone River. In the west, look in valley bottoms and near streams. Start by checking areas with showy milkweed or common milkweed patches.

5. What is the best time of year to see monarchs in Montana?

Adult monarchs are present from late May through September. The peak viewing window is July through mid-August when breeding populations are highest. Migrating monarchs pass through in late August and September, heading south. For the best odds, go on warm, sunny days with little wind. Early morning or late afternoon are good for photography as they bask in the sun.

6. How can you support monarch conservation in Montana?

Plant native milkweed (like showy milkweed or swamp milkweed) in your garden. Avoid pesticides and herbicides. Report your sightings to Monarch Watch to help track populations. If you want to bring monarchs closer, consider creating a butterfly garden with nectar plants like purple coneflower, aster, and goldenrod. Many Montana conservation groups offer free milkweed seeds.

7. What resources or gear can help with monarch spotting?

A good field guide (like the Peterson or Kaufman guides) is helpful for distinguishing lookalikes. A pair of binoculars with close focus (8x32 or similar) lets you see wing details from a distance. For documenting your finds, a camera with a macro lens works well. If you want to show your support for monarchs, we have some items below that help spread awareness.

8. What do monarch butterflies eat in Montana?

Caterpillars feed exclusively on milkweed leaves (primarily showy milkweed, common milkweed, and swamp milkweed). Adults drink nectar from many flowers, including milkweed blossoms, thistles, goldenrod, and purple coneflower. To attract monarchs to your yard, plant a variety of native nectar plants and avoid chemicals.
