Butterflies of Colorado with Kids: A Nature Explorer Guide (+ Free Map)

Colorado is a wonderful butterfly state, from the sunny gardens of the Front Range to the high mountain meadows where butterflies gather at the edges of melting snow. Big Western Tiger Swallowtails sail along the creeks, Painted Ladies stream through on their long migrations, and the long-lived Mourning Cloak can even survive Colorado winters as an adult, appearing on the first warm days of spring. From walk-through butterfly pavilions to wild alpine basins, Colorado gives families a rich and beautiful world of butterflies to explore.

This guide maps the best spots to find butterflies in Colorado with kids. Give your young explorer a mission before you go with Nature Explorer Club's Butterflies of Colorado Activity Book to track every butterfly your family discovers.

Family Tips for Butterfly Watching in Colorado

• Start at a butterfly pavilion. The Butterfly Pavilion in Westminster and the Gardens on Spring Creek Butterfly House let kids see living butterflies up close — the easiest way to spark interest.
• Visit a mountain meadow in mid-summer. High places like Yankee Boy Basin and Indian Peaks bloom in July and August, drawing fritillaries, swallowtails, and alpine butterflies.
• Look for the early Mourning Cloak. This dark butterfly with cream-colored wing edges survives winter as an adult, so it's often the very first butterfly kids see in spring.
• Download the iNaturalist app. Snap a photo for an instant ID — a fun way for kids to learn species and contribute to real science.

Frequently Asked Questions: Butterflies of Colorado with Kids

Does Colorado have a state butterfly?

Yes — the Colorado Hairstreak is Colorado's official state insect. It's a beautiful purple butterfly with black borders and small orange spots, and it lives in the foothills and mountains where it depends on Gambel oak. It's a special find for young butterfly watchers.

Where can families see lots of butterflies in Colorado?

The Butterfly Pavilion in Westminster is the easiest and most reliable, with butterflies up close year-round. For wild butterflies, the wildflower meadows of Chautauqua Park in Boulder and the high alpine basins like Yankee Boy Basin are excellent in summer.

When is the best time for butterfly watching in Colorado?

Summer is the peak, especially the mountain meadows that bloom in July and August. Lower elevations and gardens have butterflies from spring through fall, and the Mourning Cloak appears on the first warm days of spring. Sunny, warm, calm days are always best.

What is the largest butterfly in Colorado?

The Western Tiger Swallowtail is among Colorado's largest and most familiar butterflies — bright yellow with black tiger stripes and a wingspan up to four inches. It's commonly seen gliding along rivers, creeks, and city parks in June and July.

How can families attract butterflies to their Colorado garden?

Plant native nectar flowers like lupine, aster, and blanketflower, and add host plants such as milkweed for Monarchs and willows for swallowtails. Provide a sunny, sheltered spot with water, avoid pesticides, and butterflies will visit through the warm months.
