Pieris rapae
In 3 days ~40% in a week ~60%
Pieris rapae is a small-to-medium-sized butterfly species of the whites-and-yellows family Pieridae. It is known in Europe as the small white, in North America and the United Kingdom as the cabbage white or cabbage butterfly, on several continents as the small cabbage white, and in New Zealand as the white butterfly. The butterfly is recognizable by its white color with small black dots on its wings, and it can be distinguished from P. brassicae by the latter's larger size and black band at the tip of the forewings.
The caterpillar of this species, often referred to as the "imported cabbageworm", is a pest to crucifer crops such as cabbage, kale, bok choy and broccoli. Pieris rapae is widespread in Europe and Asia; it is believed to have originated in the Eastern Mediterranean region of Europe and to have spread across Eurasia thanks to the diversification of brassicaceous crops and the development of human trade routes.

With luck
About 10% of wildlife watchers report a Small White sighting in Auckland on a given day, based on 112 verified sightings from GBIF citizen-science data. It is the 59th most-seen of the 689 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.
September–October and December
In those months about 20% of wildlife watchers report a Small White in Auckland on a given day, against under 5% in July, the lowest month.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Small White sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
84th of 125
Of the 125 cities where we can rate Small White sightings, Auckland ranks 84th at about 10%. The best odds are in Hanoi (Vietnam, about 40%), Ankara (Turkey, about 30%) and Daejeon (South Korea, about 30%).
Same order: Lepidoptera
The closest relatives of the Small White that you can see in Auckland (order Lepidoptera, Butterflies and Moths) are Monarch (about 30%), Oriental Leafworm Moth (about 20%) and Epyaxa lucidata (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Small White is recorded against all the insects logged in Auckland (112 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
