I have a problem with the name of the Green-banded Swallowtail. The books describe the band as blue-green (not green) and to me it looks blue (not green) but maybe its just my eyes...
They are large and distinctive butterflies that can have a wing-span of 8 cm.
The Green-banded Swallowtail flies fast but it may be seen settling on mud, some flowers and even fresh dung.
These butterflies occur all the way up the east coast from around Port Elizabeth. They may also be found in the north-eastern regions of South Africa.
