Flights of fancy await you in the Cecil B. Day Butterfly Center, where hundreds of butterflies flutter freely about in one of North America’s largest glass-enclosed tropical butterfly conservatories. The Day Butterfly Center is a living, dynamic environment in which a variety of tropical plants nourish the residents and new arrivals emerge from their chrysalides, dry their wings and begin their very first wing-beats. Every visit to the Day Butterfly Center is a new experience. The plant palette constantly matures and changes, and the butterfly population, comprising more than 50 species, fluctuates in diversity and density due to influences such as amount of available sunshine, season of the year, temperature and stability of the ecosystem.
