Cockrell Butterfly Center surrounds visitors with live butterflies inside a warm, three-story rainforest conservatory at the Houston Museum of Natural Science. Waterfalls, tropical plants, and free-flying species create the magic, while the Brown Hall of Entomology turns insects, camouflage, and life cycles into surprisingly absorbing science. Cockrell Butterfly Center works for curious adults as well as families, especially when everyone chooses a favorite discovery.
