The facility mimics a tropical ecosystem, housing butterflies primarily from Central and South America, Africa, and Southeast Asia.
A specialized laboratory allows visitors to watch the metamorphosis process inside pupae display cases.
The internal climate is maintained at a strict threshold of 80 percent humidity to ensure the survival of tropical species.
The plant life includes nectar-providing flowers specifically chosen to sustain the butterfly population, such as Hibiscus and Lantana.
The Butterfly House is part of the broader Mainau Island botanical project, which operates as a commercial entity focused on horticultural conservation.
The Schmetterlingshaus (Butterfly House) on Mainau Island is one of the largest facilities of its kind in Germany, housing approximately 1,000 free-flying butterflies from tropical regions. The structure maintains a constant climate of 25 to 30 degrees Celsius with high humidity to replicate tropical rainforest conditions. It features a diverse landscape including waterfalls, ponds, and an extensive collection of tropical plants. Visitors can observe the complete butterfly life cycle, from eggs and caterpillars to pupae, within the breeding station. The facility provides educational displays detailing the migration patterns and anatomy of over 120 different butterfly species. It is situated on Mainau Island, a private estate known for its managed botanical gardens in Lake Constance.
The central bridge overlooking the indoor waterfall provides the best backdrop for macro shots of butterflies feeding on nectar.
Wear light layers, as the high humidity and temperature inside the house can feel significantly warmer than the island's exterior climate.
Move slowly and keep an eye on the ground, as butterflies frequently land on the footpaths to absorb minerals from the damp soil.
Use a macro lens if planning to photograph the butterflies, as they are most active near the nectar stations.
Do not attempt to touch or catch butterflies that land on you; allow them to fly away naturally.
Open daily throughout the year, but visitor density increases significantly during the primary flowering seasons.
Avoid touching the butterflies or plants; walk slowly to prevent startling the insects.
