Dichorda rectaria (Grote, 1877). [7056]

| Dichorda rectaria, adult
male.
Specimen collected Jemez Springs, Santa Fe National Forest, Sandoval
Co., New Mexico, July 2005. |
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).
