A happy Julie is Julie with camera in hand and grovelling around in the grass and weeds, usually on all fours, searching for butterflies. It's amusing the number of people who stop and ask what on earth I am doing.
We're on the verge of Summer, in New Zealand, and the Cabbage Whites are already in town.
As I've done in previous years, I've planted a few cabbages for them to lay their eggs and provide food for their young.
Cabbage Whites are not popular because of their food requirements and therefore eating people's precious cabbages, it's true, but have you really taken a good look at how beautiful these butterflies are?
First of all look at the facts about them.
Species: P. rapae
Binomial name: Pieris rapae
Common name: Cabbage butterfly, white butterfly, Cabbage white. Small white. Pepe Ma
From Europe and North America, they have been in New Zealand since about 1930 and now found throughout the country. It is suspected that it first arrived in New Zealand in the summer of 1929-30, it was first recorded in Napier in March 1930. It quickly spread all over New Zealand by the autumn or 1936, however there seem to be 'jumps' in its dispersal over those few years. For example, the first specimen in the South Island was in the port town of Timaru, not in the Marlborough region as one would expect by natural dispersion. So the logical conclusion is that some specimens where transported around the country along with our shared food of the cabbage family.
The butterfly has a wingspan of 45–50 mm.
Caterpillars are pests of cabbage and other plants of the Brassicaceae family.
Several parasites keep numbers in control.

I think White Butterflies are beautiful. Don't you?
I must admit, however, that for most of my life until now, I (like many other people) saw them as a pest eating my cabbage and lettuce plants. Since taking up photography in a serious way, and developing a huge love of butterflies, I have seen their splendour through different eyes.
From the first day I took a photo of a White Butterfly with my macro lens, my love affair with these much maligned butterflies began. By laying their eggs on host plants for their caterpillars to feed on and grow into butterflies, they are only doing what nature has hard-wired them to do. That we like to eat cabbages, lettuces and similar, is certainly not the butterfly's fault.
The small white (Pieris rapae) is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. It is also known as the small cabbage white and in New Zealand, simply as white butterfly.
The names "cabbage butterfly" and "cabbage white" can also refer to the large white.
The butterfly can be distinguished by the white color with small black dots on its wings. They are distinguished from the smaller size and lack of the black band at the tip of their forewings.
The White Butterfly is suspected tho have first arrived in New Zealand in the summer of 1929-30. It was first recorded in Napier in March 1930.
It quickly spread throughout New Zealand by the autumn of 1936, however there seems to be 'jumps' in its dispersal over those few years. For example the first specimen in the South Island was in the port town of Timaru, not in the Marlborough region as one would expect by natural dispersion.
The logical conclusion is that some specimens where transported around the country along with our shared food of the cabbage family. This is the way it is suspected that the White Butterfly made it to New Zealand (just like North America in the years before and Australia in the years after). No one is sure whether the New Zealand stock came from Hawaii, North America, Europe, Asia or a combination, but most likely it travelled as a pupa in diapause as this would give it the best chance of surviving in a cold store.
It is recorded as having up to 5 generations a year in the north and 2 generations in the south.
The White Butterfly is considered a pest in New Zealand, so several parasites (Ichneumon's, the wasps Pteromalus Puparum and Apanteles glomeratus) have being released to control it.
Unfortunately they are negatively effecting other species of butterfly, especially the Red and Yellow Admirals and the Monarchs.
The White Butterfly has characteristics not seen in other New Zealand Butterflies, namely the aforementioned diapause, a seasonal difference in size, and less black markings on the spring generation.
The Maori name "Pepe Ma" is translated from the English name.
