They arrive on the island of Mainau as pupae every week. The remaining 30% reproduce directly in the butterfly house on the respective food plants, where the development from egg to caterpillar (larva) and chrysalis to the finished butterfly can be observed.you will find a wide range of Mainau souvenirs in the store. Coffee, ice cream and drinks are available all year round in the bistro area. During the season you can also get a small snack.
