Sevenmile Creek, 8 km NW of Helena, Lewis and Clark County, Montana, USA
September 14, 2021
Pontia, too drab for P. beckerii. At least 2 present, nectaring on Sisymbrium loeselii. Photos of male. Ruderal floodplain community with Kochia scoparia, Chenopodium simplex, Chenopodium berlandieri, Helianthus annuus, and Cleome serrulata. Midday to early afternoon, sunny, 66 F to 73 F, gentle to fresh W breeze, good air quality.

Elevation ca 4000 feet. Disturbed riparian corridor on stream restoration site within a patchwork of native and non-native grassland.

Pontia occidentalis?

Moved based on closer study
Moved from Checkered Whites.

In Glassberg's (2001) field guide he writes, "On the FW marginal black spotband, Western males have a set of five or six spots, while Checkered males almost always lack spots 3 and 5 (counting down from the forewing apex)." Based on that description, I am moving this to P. protodice - which should be the expected species in the valley habitat of this site.
