Cecil B. Day Butterfly Center

His wife, Deen Day Sanders, donated artwork and financial assistance to Callaway Gardens in his honor.

The butterfly center is a 7,300-square-foot (680 m2) glass dome that rises to 35 feet at its peak, allowing sunshine inside whenever clouds are absent.

[2] Signs are posted at the exits with a United States Department of Agriculture warning against removing any butterfly, insect or plant material from the premises.

[1] The conservatory simulates a tropical ecosystem; the temperature is maintained at approximately 80 °F (27 °C) and 74% relative humidity, ideal conditions for the specimens.

The butterflies are sent to the gardens via US Mail, FedEx or UPS in small cardboard boxes padded with cotton.

[3] The popular iridescent blue Morpho rhetenor emerges in the month of September and several special butterfly events are held.
