Several sinistral specimens have been found at Cape Town 
(Lightfoot). 
This species, said to have been introduced into Cape Town by 
Mons. Dastre, as a table delicacy, about 1870, has now become one 
of the greatest pests in gardens throughout the Cape Peninsula. It 
appears also to thrive on the peculiar local type of wild herbage, 
and thus threatens to oust many of the rarer, indigenous species 
from their last foothold, by eating them out of house and home.
