## About

Located within Faust Park in Chesterfield, the Sophia M. Sachs Butterfly House transports families into an 8,000-square-foot glass conservatory maintained at a balmy 85 degrees and 80 percent humidity all winter long. More than 1,500 tropical butterflies representing 60 global species flutter freely among blooming orchids, tropical palms, and trickling waterfalls.

Children can stand beside the Emergence Window to watch caterpillars metamorphose and newly emerged butterflies dry their wings before taking flight. The indoor Lopata Learning Lab offers hands-on insect discovery tables with giant millipedes, stick bugs, and stag beetles. Due to USDA butterfly containment rules, umbrella strollers or baby wraps are recommended over bulky jogging strollers. Family restrooms with diaper changing counters and stroller parking are available in the lobby.
