After more than twenty years the butterfly house has become the place for new parents to bring their own children, after they themselves had visited it when they were young. This is only an indication of how much the experience of being able to come into direct contact with butterflies can remain alive in the hearts of people. The butterflies of Butterfly Arc belong to the tropical habitats of Africa, Asia and America and arrive weekly from their countries of origin in the form of a chrysalis. The caterpillars, before they became chrysalises, have been bred by local breeders.

Except for demonstrations during national holidays, the visitors have the possibility to make use of the tactile and spinning laboratories, which allow them to directly interact with some six-legged guests of the museum under the supervision of an instructor, or learn the technique of unravelling the cocoons and obtaining a silk skein. Throughout the year original events and initiatives are organised. In order to remain up to date and obtain special offers register as friends of the museum on the Esapolis website.
