The green-veined white (Pieris napi) is a butterfly of the family Pieridae. A circumboreal species widespread across Europe and Asia, including the Indian subcontinent, Japan, the Maghreb and North America.

Like other "white" butterflies, the sexes differ. The female has two spots on each forewing, the male only one. The veins on the wings of the female are usually more heavily marked. The underside hindwings are pale yellow with the veins highlighted by black scales giving a greenish tint, hence green-veined white. Unlike the large and small whites, it rarely chooses garden cabbages to lay its eggs on, preferring wild crucifers. Males emit a sex pheromone that is perceptible to humans, citral, the basic flavor-imparting component of lemon peel oil.
Some authors consider the mustard white and West Virginia white of North America to be conspecific with P. napi or consider P. napi to be a superspecies. Despite this, the American butterflies, unlike P. napi, cannot successfully... Wikipedia →

Possible
About 20% of wildlife watchers report a Green-Veined White sighting in Pyrénées National Park on a given day, based on 197 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 32nd most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April and September
In those months about 30% of wildlife watchers report a Green-Veined White in Pyrénées National Park on a given day, against under 5% in November to February, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Green-Veined 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.
8th of 19
Of the 19 parks where we can rate Green-Veined White sightings, Pyrénées National Park ranks 8th at about 20%. The best odds are in Biebrza National Park (Poland, about 40%), Białowieża National Park (Poland, about 30%) and Bavarian Forest National Park (Germany, about 30%).
Same genus: Pieris
The closest relatives of the Green-Veined White that you can see in Pyrénées National Park (genus Pieris, Garden Whites) are Large White (about 10%) and Small White (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Green-Veined White is recorded against all the insects logged in Pyrénées National Park (197 verified sightings from 2019 to 2026), 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.
