Originally from South Africa the pelargonium butterfly also known as the geranium bronze (cacyrens marshalli) had been introduced into some areas of Europe mostly the Mediterranean regions and has spread more rapidly since the 1990s, the caterpillar or eggs could have been on the undersides of pelargonium leaves when they were transported as cultivated garden plants, but this is not certain.

They are regarded as pests and an invasive species to pelargoniums and geraniums and can cause a lot of damage especially during Summer when flowers and flower buds can be completely destroyed which can also lead to disease and even death.

Recorded Areas of Europe that have been inhabited by the pelargonium butterfly include Spain, France (Mediterranean regions), Italy, Portugal, Balearic Islands, Canary Islands, Malta, Greece and Turkey and the UK , but they may be restricted to certain districts.

The wing decorations of the butterfly are brown with a black outline around the edge interlaced with white, underneath the wings it is greyish brown in colour with blotches and a thin tail.
