Butterfly House Maximilianpark

Up to 80 different butterfly species from the tropical regions of South and Central America, Africa, Thailand, Malaysia and the Philippines all live for the course of one season in NRW’s largest tropical butterfly house. The butterflies fly freely throughout the 450 sqm tropical paradise. Marvel at night butterflies the size of a palm like the Atlas silk spinner and see how it remains almost motionless throughout its day’s sleep.
The breeders comply with the requirements of the International Convention for the Protection of Species (CITES), which prohibits any wild capture of protected species. These tropical butterflies come exclusively as offsprings from butterfly farms and are not protected. During the course of a season, up to 80 different butterfly species from the tropical regions of South and Central America, Africa, Australia and Asia can be seen.

The paid visit to the butterfly house is worthwhile, as you can see a very large selection of different types of butterflies here.

Fantastic, the butterflies 🦋 flutter around everywhere, sometimes huge and within reach (don't take it literally)
Also great for children, as long as they have their fingers under control 🧙
