Neophasia menapia, the pine white, is a butterfly in the family Pieridae. It is found in the western United States and in southern British Columbia, Canada. It is mostly white with black veins and wing bars. The species is similar to Neophasia terlooii but their ranges only overlap in New Mexico.
The wingspan is 42–50 millimetres (1.7–2.0 in). Its habitats include pine forests and Douglas fir forests in northern coastal California. The host plants are Pinus species, Pseudotsuga menziesii, Tsuga heterophylla, Abies balsamea, Abies grandis, and Picea sitchensis. Adults feed on flower nectar from rabbitbrush, other yellow-flowered composites, and monarda.
Neophasia menapia are a univoltine species that lay their eggs on live pine needles, as stated by a scientific research paper ("Phylogeography and the population genertics of pine butterflies") that details the differences between Neophasia. Wikipedia →

With luck
About 10% of wildlife watchers report a Pine White sighting in Great Bear Rainforest on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 124th most-seen of the 235 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report a Pine White in Great Bear Rainforest on a given day, against under 5% in October to June, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Pine 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.
Among the best
Of the 6 parks where we can rate Pine White sightings, Great Bear Rainforest ranks 5th at about 10%, level with the leaders once rounded. The best odds are in Redwood National Park (United States, about 10%), Grand Teton National Park (United States, about 10%) and Olympic National Park (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Pine White is recorded against all the insects logged in Great Bear Rainforest (11 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.
