The butterfly is one of the favourite themes in Art Nouveau. It is often associated with the soul or the fleeting nature of life. Frantisek Kobliha frequently used this motif to decorate books. In the centre of the engraving, against a backdrop of clouds, a butterfly is depicted in flight with its open wings. The surface of the wings is dark, while the edges are patterned with light colours and black spots. On the upper wings, there are arched light stripes. At the bottom of the engraving, wide grass stems are depicted swaying in the wind.
