New Zealand [sửa]
R. cardinalis was accidentally introduced to New Zealand, though they are no longer very common. An outbreak of cottony cushion scale in California took place in the late 19th century, which lead to some being imported from New Zealand in 1888 to help protect citrus trees. They are red with black markings, and about 4mm long.
R. cardinalis was introduced into Californian citrus orchards in late 1888.
