Eupithecia gilvipennata

Eupithecia gilvipennata is a moth in the Geometridae family. It is found along the Pacific coast from British Columbia, through Colorado to California and Arizona.

The wingspan is about 25 mm. The forewings are largely black brown with indications of ochreous shading around a small discal dot and at the apex of the wing. The hindwings are dirty white with broad blackish shading along the outer and inner margins. Adults are on wing very early in spring, from late February to early March in central California and from late April to early May farther north.

The larvae feed on the flowers of Arbutus pungens. They are cryptically patterned and coloured to match the flowers of their host plant.
