Pieris rapae
In 3 days ~50% in a week ~80%
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.

GBIF citizen-science records
It is estimated from how often the Small White is recorded against all the insects logged in Minneapolis [Saint Paul] (434 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.
