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 Redwood National Park on a given day, based on 18 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 20th most-seen of the 101 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report a Pine White in Redwood National Park on a given day, against under 5% in October to May, the lowest months. That is one of Redwood National Park's driest months, with almost no rain against 360 mm in January.
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.
Yes
Of the 6 parks where we can rate Pine White sightings, Redwood National Park has the highest daily chance: about 10%. Next come Grand Teton National Park (United States, about 10%) and Olympic National Park (United States, about 10%).
Same family: Pieridae
The closest relatives of the Pine White that you can see in Redwood National Park (family Pieridae, Whites, Yellows, and Sulphurs) are Margined White (about 20%) 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 Pine White is recorded against all the insects logged in Redwood National Park (18 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.
