The poem Sang Kupu-kupu tells the butterfly's behavior toward the flowers in the garden. Butterflies love to praise and seduce to express their love for the flowers that they land on. The complacent flower forgot about itself. In such circumstances, the butterfly will suck its honey freely and leave it to look for other flowers.

A flower that has been stained can do nothing, only hope for the mercy of the Butterfly that has stained it, and hope that the Butterfly will return. The flower’s wait was just in vain, what was awaited never came. Finally, the flower died in sorrow.

On his way to find a new victim, Butterflies saw a Grasshopper perched on a wooden tree. He saw the movements and beauty of the sweet Leaf Grasshopper, so he immediately fell in love. With hope he approached the Leaf Grasshopper, he greeted her with a sweet and seductive greeting.

The grasshopper was surprised and blushed at the butterfly's seduction, then flew away from the place. The butterfly soon followed and was about to openly confess his love, but he was afraid of the Grasshopper family. He had felt that the Grasshopper family would not approve of their relationship. Since then the butterfly's mind was only focused on the grasshopper alone, his body was getting thinner day by day because he was holding back his longing. That is the reward for his behavior toward flowers
