Panemeria tenebrata

Panemeria tenebrata, the small yellow underwing, is a moth of the family Noctuidae. The species was first described by Giovanni Antonio Scopoli in his 1763 Entomologia Carniolica. It is found in Europe but is missing in northern Scandinavia, in Portugal, in central and southern Spain, as well as on most Mediterranean islands, except Sicily. In the east, the range extends to the Ural mountains, but the east distribution limits are still insufficiently known. Occurrence in Asia Minor is uncertain, but it is known from Jordan and Israel.
