The Sooty Blue is a small little butterfly with a wingspan of around 2 cm. Males are more blue on top of the wings than females.
Although this is one of the vast family of 'blue' butterflies they do at first appear to be white with speckled markings. It is only when they open their wings, which is not often (other than when they are flying of course!) that the blue is evident.
This butterfly is very common and is most often found fluttering low over lawns.
The Sooty Blue is also known as the African Grass Blue.
