For safety reasons, strollers are restricted in the Butterfly House. No strollers allowed in the conservatory due to USDA regulations.



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. 

The Native Butterfly Garden

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 Exhibit Hall

The Exhibit Hall is where you'll find Small Wonders, a living exhibit focusing on the habitats and lifestyles of various invertebrates, as well as our immersive dome of Orange-headed Cockroaches.

Open 10 a.m. to 4 p.m.  |  Last admission at 3:30 p.m. | Closed Mondays

Summer Buggin' at the Butterfly House

We are "buggin' out" at the Butterfly House this summer! Join us as we host a variety of activities that celebrate these amazing creatures. Get wiggles out and ants out of your pants during Summer Buggin'! Join us to learn about bees, ladybugs, fireflies, and of course BUTTERFLIES through interactive exploration and live animal encounters.

Experience the Butterfly House after hours during Summer Buggin' Nights! Go on a "Bug Hunt," then uncover mysteries as you explore our Tropical Conservatory and our Native Butterfly Garden.

Go on a Bug Hunt as you explore our Native Gardens and the park around the Butterfly House. We will be looking for native insects of all types, including fireflies, ladybugs, grasshoppers, caterpillars, beetles, and much more. All insects will be released at the end of the hunt.
