The habitat hosts species with wingspans that can reach up to 20 centimeters.
The enclosure maintains a constant tropical climate, often exceeding 25 degrees Celsius with high humidity throughout the year.
Butterflies are imported to the facility in the form of pupae, which are then monitored in an incubation cabinet before emergence.
The facility serves as a pedagogical space where visitors can observe the metamorphosis process in a live, controlled setting.
The butterflies are fed using specialized feeding stations that replicate natural nectar sources.
Butterfly House Diana is a tropical indoor butterfly habitat located at the summit of Friendship Hill in Karlovy Vary. It functions as a controlled environment featuring free-flying exotic butterfly species from tropical regions such as Southeast Asia, South America, and Africa. The facility is situated directly adjacent to the historic Diana Lookout Tower. The ecosystem maintains specific temperature and humidity levels to support the butterfly life cycle from pupa to adult. Visitors walk through a space where butterflies are not restricted by enclosures, allowing for close-range observation. The house is part of the broader Papilonia network of butterfly exhibits in the Czech Republic.
The central feeding stations where butterflies congregate in high density.
Wear light-colored clothing to increase the likelihood of butterflies landing on you.
Move slowly and avoid sudden gestures to prevent disturbing the free-flying butterflies.
Ensure your camera lens is clean before entering as the high humidity can cause immediate fogging on equipment.
Do not wear strong perfumes or colognes, as these can confuse or repel the butterflies; do not try to chase or catch the specimens.
Open daily year-round, including all holidays; check local updates for rare maintenance closures.
Do not touch the butterflies with your hands as their wings are extremely fragile; keep bags and backpacks closed to prevent butterflies from accidentally flying inside.
