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.

The species is similar to Neophasia terlooii but their ranges only overlap in New Mexico.

[5] Adults feed on flower nectar from rabbitbrush, other yellow-flowered composites, and monarda.

[4] 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.
