Exhibition: butterflies of the world
The collection was acquired in its entirety by Irun City Council in 2006 from its promoter and owner Manuel Aguirresarobe, who collected the Spanish butterflies in the exhibition himself. The specimens from other parts of the world are the result of exchange agreements with colleagues and institutions from around the world. There is a description with each specimen, containing key characteristics. The visit ends with a documentary video on the biological cycle of the butterfly. Altogether, nearly 7,000 butterflies are on display.
