The tropical conservatory is the heart of the Butterfly House. Its carefully controlled environment houses nearly 2,000 tropical butterflies in free flight. As many as 80 butterfly species and 150 tropical plant species are exhibited. Few moments in nature are as magical as watching a butterfly emerge from its chrysalis. This rarely seen transformation becomes an everyday occurrence in the "Miracle of Metamorphosis." Hundreds of chrysalides from around the world are on display with butterflies emerging before your very eyes.

Our outdoor Butterfly Garden is a "backyard" demonstration garden. Plants were carefully selected to provide habitat for the animals in Faust Park and to serve as host plants for caterpillars and nectar sources for butterflies.

The Bayer Pavilion sits in the Butterfly Garden and provides a favorite location for many private celebrations. For information on private events at the Butterfly House call (314) 577-0888 x 3.

Nature T.R.E.K. is a sensory nature trail where families explore the natural habitats of plants and wildlife. Children use their senses in the following ways: sight to find colors and shapes in the garden, touch to feel a variety of textures, smell to experience fragrant plants, and hearing with instruments that make animal calls. The highlight of Nature T.R.E.K. is the climbable honeycomb. Learn more

Join us at 10:30am on the 2nd Sunday of every month for a full-length showing of  "Beauty on the Wing: Life Story of the Monarch Butterfly," a 56-minute narrated film that unfolds along the shores of Cape Ann and in the heart of Mexico’s forested volcanic mountains. Every stage of the butterfly’s life cycle is experienced in vibrant close-up, from mating to egg to caterpillar to adult, and set against the backdrop of sea and forest, sun and wind.

Overhead a graceful arch heralds the beginning of a magical experience. Underfoot, the plaza is constructed of butterfly-shaped paving stones. Many of the stones, inscribed with personal messages, tributes, and memorials, are gifts from families and individuals. There is still space to add your family milestones.

A 30-foot long caterpillar sculpture sits among native prairie plants just outside the entrance. It was created by artist Bob Cassilly and presented to the Butterfly House by Lucy and Stanley Lopata.

Surrounded by seasonal gardens, this sculpture presents a great photo opportunity for families. The 28-foot tall butterfly was created by St. Louis sculptor Bob Cassilly and given to the Butterfly House by Rosemary and Joe Shaughnessy in honor of their grandchildren.
