Butterflies - Geranium Bronze (Cacyreus marshalli)

The Geranium Bronze is native to South Africa and has spread to Europe with imported Pelargonium plants. It is now common in parts of southern Spain, France and Italy with occasional records from Holland, Belgium and more recently England.

In the summer of, John Carter discovered this Geranium Bronze butterfly on his Pelargonium plants in his garden in Pillerton Priors a few days after purchasing the plants from a local garden centre. This female (see photo below) had clearly mated with a male and was busily laying eggs on the buds of his plants.
