Habitat

Widespread and common in urban areas where it is a pest of cruciferous crops. It occurs in all States and Territories of Australia but it is more widespread in southern areas.

Notes

An introduced European species, it was first recorded in Victoria and Australia in 1937. The cylindrical green larvae can be a major pest of Brassica crops but the butterfly is also often common wherever cruciferous weeds occur. The larvae pupate on the host plant or wander off, often pupating on nearby fences or walls. The pupae are usually green and are supported by a central girdle of silk but can be greyer if they have pupated on wooden fences. In the 1940’s two species of braconid wasps were introduced as biological control agents of the Cabbage White Butterfly. These wasps, along with native wasp and fly parasites, have undoubtedly helped reduce the abundance and economic importance of this butterfly.

My name is Meadhbh O'Donnell. I'm 17 and I live in Co.Donegal in Ireland. Im sitting my leaving Cert. this year and as one of my seven subjects I'm studying Agricultural Science. As part of this project we have to identify 10 animals that are used in agriculture today. My teacher suggested we wrote about the cabbage-white butterfly but i cant seem to find any relevant information on them. I know you dont usually respond to comments but i would be extremmely grateful if you could give me any information you can on the cabbage-white butterflys relevance to agriculture. I would really appreciate it. Thank you :)

Just wondering, we are doing a science project on the cabbage butterfly and we are trying to figure out if its a male or a female! It has one bright dot and a faded one.. does that mean its an old female that has layed its eggs and is about to die.. And what is the average size of a White Cabbage Butterfly or known as a Cabbage Moth.

Hi Mandy, the wingspan of the cabbage white butterfly (Pieris rapae) is 4.5 to 5 cm. Your butterfly is probably a female as the female has 2 dark spots on the fore-wing; the male has 1 black spot. There is a tendency for butterflies to have lighter markings early in the season, so this may be the reason for the lighter spot, or it could be due to natural variability. If your butterfly is mature the wing will have a pale yellow line on the back, and a line of yellow spots on each side.

Hi Meadhbh, there are a couple of links here and here with some information relating to the Cabbage White Butterfly and agriculture. For more in depth information you would need to contact the Department of Primary Industries who undertake research in Victoria into agriculture and related pests.

Hi. I am doing a project on the cabbage butterfly and I was wondering when does it breed and how long is its lifespan. This is really important because I can't find it on any other site.

Hi Lauri & Laura,

Thanks for your comments. You can find out more about the Cabbage White Butterfly in Michael F. Braby's book called Butterflies of Australia (CSIRO Publishing Melbourne, 2000, vol. 1) which contains a section with relevant information called ‘Life Style and Behaviour’ pp. 343-344. This would be accessible at most good libraries. Another website also has information about the life cycle of the butterfly: Pieris rapae.

Have just been photographing some butterflies in our property (Wantirna Sth) including a cabbage white, Pieris rapae (Female)(I at last got one to stay still.) online found your site to confirm identity, but also noted the 'large white' Pieris brassicae Cabbage white. USA, et al size appeared to be the major diff. So i thought for people looking for names etc a comment (in the small white, re the fact that a different species is also called the 'same name. We have become more cosmopolitan in recent years.(in fact we had a Biol teacher from USAS for several yrs here at my old high School alongside me. so differences could be of benefit to some, you might agree!Ps I also had a good shot of an orchard swallowtail (Male) as well landing just as i finished with the white.

I was wondering is the cabbage white butterfly the most common butterfly in the world and if not then what is please answer i need this information for a school project

It is found alot of places so I think it might
Discovery Centre 9 March, 2012 11:10
Hi Maegan, it is hard to give a definitive answer on this question. Certainly the Cabbage White Butterfly is likely to be one of the most common butterfly species in the world. The Lepidopterist's Society suggest that the Painted Lady Buttefly, Vanessa cardui may be the most widespread in terms of its worldwide distribution.

Hi, is there any information that I can relate Pieris Rapae to the climate change? I'm working on phenology of Pieris Rapae.
reply
Discovery Centre 23 April, 2012 11:15

Hi Damien - this is an interesting question; we have checked with the Manager of our Live Exhibits team, and he has said the following: In our experience, despite its abundance, there's not that much information out there on Pieris rapae. There has been some work done on the potential effects of climate change on Australian butterflies by a number of researchers, but P.rapae doesn't appear to have been included in their research. The best person to ask might be Michael Braby at the Northern Territory Department of Natural Resources, Environment, the Arts and Sport.

We hope this helps
