Scoparia declivis is a species of moth in the family Crambidae. It is endemic to New Zealand.
Scoparia declivis was described by Alfred Philpott in 1918. However the placement of this species within the genus Scoparia is in doubt. As a result, this species has also been referred to as Scoparia (s.l.) declivis.
The wingspan is 28âÂÂ32 mm. The forewings are fuscous-brown, irrorated with white. The basal area is pale up to the first line. This first line is whitish. The hindwings are pale whitish-ochreous. Adults have been recorded on wing in February.
