IdentificationA small (2.5cm wingspan) yellow-buff geometrid moth. The forewings are crossed by poorly defined and somewhat sinuous brown antemedian, median and postmedian lines, the later most prominent, All are thicker and darker where they meet the costa. There is a dark brown blotch on the outside of the postmedian line midway, a second one at the costa above, and a terminal line comprised of a series of dark dots or short dashes. The hindwings are crossed by faint partial antemedian and more complete median lines. Both wings are covered with a light dusting of dark brown scales. Male antennae are broadly bipectinate. Similar to Macaria occiduaria, which is brighter yellow with more sharply defined dark markings and lacks the dusting of dark scales.
