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

Iowa is a wonderful butterfly state, where restored tallgrass prairies, wetlands, and gardens host a beautiful variety. Monarchs drift over milkweed-filled prairies before their epic fall migration to Mexico, big Eastern Tiger Swallowtails sail near the woods and water, and quick little skippers dart from flower to flower. Iowa's rare native prairie remnants also support specialized butterflies you won't find just anywhere. From walk-through butterfly wings to wild prairie preserves, Iowa gives families a rich world of butterflies to explore.

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

Family Tips for Butterfly Watching in Iowa

• Visit the Reiman Gardens Butterfly Wing. Hundreds of butterflies fly freely in a warm indoor garden — they may even land on your child, and it's open year-round.

• 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 Iowa with Kids

Does Iowa have a state butterfly?

Iowa does not have an official state butterfly, but the Monarch is one of its most beloved and important. Monarchs migrate through Iowa each fall on their way to Mexico, and they depend on milkweed, which grows across the state's prairies and meadows.

Where can families see lots of butterflies in Iowa?

The Reiman Gardens Butterfly Wing in Ames is the easiest and most magical, with hundreds of butterflies year-round. For wild butterflies, the tallgrass prairies at Neal Smith, Hayden, and Kalsow are excellent in summer.

When is the best time for butterfly watching in Iowa?

Summer is the peak, when prairies and gardens bloom and swallowtails, fritillaries, and Monarchs are most active. Late summer and early fall bring the famous Monarch migration. The indoor butterfly wing is wonderful year-round, even in Iowa's cold winters. Warm, sunny, calm days are always best outdoors.

What is the largest butterfly in Iowa?

The Eastern Tiger Swallowtail is among Iowa's largest and most familiar butterflies — bright yellow with black tiger stripes and a wingspan up to five inches. Its caterpillar is remarkable too: it looks like a tiny green snake with big fake eyespots to scare away birds.

How can families attract butterflies to their Iowa garden?

Plant native nectar flowers like bee balm, blazing star, and coneflower, and add host plants such as milkweed for Monarchs and dill or parsley for Black Swallowtails. Provide a sunny, sheltered spot, avoid pesticides, and butterflies will visit all summer.
