Cabbage White Butterfly
(Pieris rapae)
The Cabbage White butterfly is commonly
found throughout Australia after being accidently
introduced from Europe in the 1920's. The Cabbage White
Butterfly has a black body with white wings and each wing
has black spots near its centre. The sex of the Cabbage
White butterflies can be easily determined as the female
has two dark spots mid-wing and the male has only one. The
first official recording of the Cabbage White in Australia
was made in Melbourne in 1929. The Cabbage White
caterpillars are silky green and are considered to be a
serious agricultural pest. They tunnel into the interior
of vegetables such as cabbages, cauliflower, broccoli,
turnips and other plants found in vegetable gardens, to
feed. Two species of braconid wasps were introduced into
Australia as a biological control agent to help reduce the
butterfly numbers. The wasps have helped considerably in
the reduction of these pests. The female Cabbage White
butterflies lays her eggs on vegetable plants. The
caterpillars feed from under the leaf before tunneling
into the plants centre.
