## Summary

The geranium bronze or brun des pélargoniums in French (Cacyreus marshalli), is a butterfly in the family Lycaenidae.
The geranium bronze butterfly is native to South Africa. The butterfly was first introduced to Europe in the late 20th century, where it has quickly spread to many southern and eastern European regions. Since its introduction to Europe, the geranium bronze butterfly has become a pest to cultivated Pelargonium and Geranium plant species. Currently, efforts are being made to contain the spread of the geranium bronze butterflies as well as to determine the most effective pesticide for the species.
