in detail

They are a symbol of lightness, freedom, transformation and new life. We are delighted to be able to offer a year-round presentation of the diversity and multi-coloured variety of these animals, which are an important part of nature. Butterflies are wonderful animals that evoke a number of positive associations.

Visitors can learn about the complete methamorphosis – from eggs to butterflies. Of approximately 50 laid eggs, only about 3 butterflies will emerge successfully. The exhibition reveals the secret of butterflies' colours. The scales on the wings, which are of different shapes and colours, resemble roof slates. They contain pigments that absorb light of a particular wavelength. The exhibition also covers the butterflies' enemies, and the different means of butterflies' defence, i.e. camouflage and mimicry.

Slovenia boasts extraordinary diversity of butterflies and moths. There are more butterfly species in a single karst meadow than in the whole of the United Kingdom. A major focus of the exhibition is on the endangered species and their conservation. In Slovenia, there are 223 butterfly and moth species listed as endangered. Destroying and drying of the wetlands and wet meadows and overgrowing pose the main threats. Agriculture intensification and grassland improvement, such as fertilisation, earlier and continuous cutting, and pesticide use, are among the main reasons for the decline in the abundance of butterflies.

Butterflies are extraordinary creatures, which provide us with plenty of aesthetic and photographic challenges. The exhibition features a number of interesting stories – one of them is about the Japanese Oak Silkmoth – animals escaped and settled throughout Slovenia!
