Geranium Bronze Cacyreus marshalli
This butterfly is in fact a South African native which has established itself in Europe. As the climate gets warmer some European butterflies are beginning to move north and this one was first seen in Britain in 1997 - the first new sighting for 80 years.
In Spain they were plentiful even in March and at first I thought they must be a day flying moth - until one settled very briefly. In Italy in September again they were plentiful sometimes on Perlagonium but mostly on Erigeron karvinskianus (Mexican Fleabane).
