Identification
Distinguished from other western North American Syngrapha by its geographic range and period. Specimens require genitalia examination or molecular analysis for definitive separation from closely related such as Syngrapha cachena and Syngrapha alticola. The combination of July flight period in high-elevation and northern coastal is suggestive but not diagnostic.

Appearance
Wingspan 34–36 mm. Forewings display the characteristic looper pattern with a distinct silver or pale marking. The specific wing pattern details for this have not been separately described from related Syngrapha species.
Habitat
Montane and subalpine zones; northern coastal forests. Associated with Vaccinium-dominated understory in coniferous and mixed woodlands.
Distribution
Western North America: extreme northern British Columbia and Haida Gwaii ( Charlotte Islands), south to southern Oregon, east to western Wyoming, Montana, and western Alberta.

Similar Taxa
- Syngrapha cachenaOverlapping western montane distribution; requires genitalia dissection for reliable separation
- Syngrapha alticolaSimilar preference in western mountains; distinguished by subtle genitalic differences
- Syngrapha rectangulaBroadly sympatric in western North America; rectangula has more extensive transcontinental range

Taxonomic history
Originally described as Plusia orophila Hampson, 1908; transferred to Syngrapha upon reclassification of the Plusiinae. The basionym reflects historical placement in the Plusia, which is now restricted to Old World .
