Eois percisa

Eois percisa is a moth in the family Geometridae. It is found in Peru.

The wingspan is about 21 mm. The forewings are pale yellow, with lilac-grey wavy cross-lines parallel to the oblique outer margin. In the basal half of the wing (including the central fascia) these lines are thickened and confluent, obscuring the ground-colour except on the costa. The hindwings are similar to the forewings, but the basal third is grey and contains a large black cell-spot and a pale yellow band beyond it, which is visible (but less prominent) on the forewings also.
