Protorthodes incincta
(Morrison, 1874)
banded Quaker moth
Protorthodes incincta, commonly known as the banded Quaker , is a noctuid moth native to western North America. display remarkable color , ranging from pale whitish-grey to blackish-grey with intermediate brown, orange, and grey forms. The species occupies dry grassland and open forest across the Great Plains, Rocky Mountains, and adjacent regions. period extends from early June through early October, with larval stages feeding on herbaceous plants including legumes.

Identification
Distinguished from similar Protorthodes by: (1) more irregular pale subterminal line; (2) concentration of dark sagittate marks to subterminal line specifically in area to spot; (3) maculation pattern details; (4) structure; (5) male genitalia characteristics. Formerly recognized forms 'P. indra' (pale xeric morph) and 'P. daviesi' (high-contrast morph) now synonymized under P. incincta.

Appearance
Forewing length 11–14 mm. Ground color highly variable: pale whitish-grey through shades of brown, orange, and grey to blackish-grey. Pale subterminal line irregular in shape. Dark sagittate (arrow-shaped) marks concentrated to subterminal line in area to spot. Palest forms occur in xeric regions of Nevada, Arizona, and New Mexico. Most contrastingly marked forms found in southern Wyoming, Colorado, and northern New Mexico.
Habitat
Dry open including western Great Plains grasslands, dry open forests of the Rocky Mountain region, Great Basin scrublands, American Southwest aridlands, and relict prairie patches in the Great Lakes region. Occurs in xeric to semi-arid environments.
Distribution
North America: western Great Plains, Rocky Mountains (dry open forests), Great Basin, American Southwest, with eastward range extensions into relict prairie areas of the Great Lakes region. Canadian records: Alberta, Manitoba, Saskatchewan.

Behavior
activity typical of Noctuidae. Specific such as patterns, mating, or defensive responses not documented in available sources.
Ecological Role
Larval herbivore in grassland and dry forest . Member of noctuid in western North American arid and semi-arid . Specific ecological functions (pollination, prey resource, etc.) not quantified.
Human Relevance

Misconceptions
Formerly recognized as multiple : pale southwestern forms described as 'P. indra' and high-contrast Rocky Mountain forms as 'P. daviesi' are now synonymized under P. incincta, representing intraspecific color rather than distinct species.

Taxonomic history
Originally described as Mamestra incincta by Morrison in 1874. Transferred to Protorthodes. Formerly recognized distinct forms 'indra' and 'daviesi' now treated as synonyms representing color morphs.
Color polymorphism
Extensive geographic color variation correlates with : palest forms in most xeric environments (Nevada, Arizona, New Mexico), most patterned forms in southern Wyoming, Colorado, northern New Mexico.
