FWL = 16-20 mm; smaller in Great Basin FWL = 16-18 mm (1)
Evenly colored pale yellow forewings and fringe; hindwings white with moths from some locations exhibiting varying degrees of fuscous shading toward outer margin; male antenna beadlike. (1)

MONA Fascicle does not address forewing transverse lines, which is very uncharacteristic of the fascicle in describing species within this genus. None of the images of grandis within the fascicle appear to exhibit forewing transverse lines. There are images of grandis at MPG that do show AM/PM forewing lines showing as small dark spots. Pacific Northwest Moths actually describes grandis as sometimes having the forewing PM line indicated by black dots on the veins, however the single image showing there does not exhibit a PM line.

Copablepharon spiritum is typically larger, not as yellow, has bicolored fringe, and the male antenna are biserrate. (1)
Copablepharon flavum has more of a chalky yellow forewing with paler yellow longitudinal streaks, the hindwing is yellowish-white, and the male antenna is biserrate. (1)
Copablepharon serratigrande males have deeply biserrate antenna. (1)
Copablepharon sanctaemonicae has distictive greenish-yellow forewing, hindwing that is mainly fuscous or with fuscous band or series of spots on the PM line, and is confined to coastal dunes in SW California; is otherwise structurally similar and may be form of same species. (1)
