Dichorda rectaria rectaria is a fairly widespread moth, occurring in parts of Texas, Kansas, Nebraska, North Dakota, Arizona, Utah, and Idaho. Like other Dichorda species, D. rectaria is relatively large among the N. American Geometrinae, with average wing length of approximately 15 mm. It is distinguishable from Dichorda iridaria by the absence of white-washed striations on the green wing ground color, and by a distinctly straight antemedial line on the forewing.
Wings are a rather bluish-green shade, notably angulate at the forewing tips, and marked by broad, sharply defined white postmedial lines that continue from the forewing onto the hindwing. White lines are typically edged with a brighter green on the inner side facing the median space between the am and pm lines. The antemedial line is nearly as broad and clear on the forewing, but is lacking altogether on the hindwing (a trait shared with other Dichorda species).
