The Glaucous Shears (Papestra biren) is a moth of the Noctuidae family. It is found in most of Europe, but not in the Southern parts of the Iberian Peninsula, Italy and Greece. Outside of Europe it is found in Kashmir and Eastern Asia. It was introduced in Newfoundland in 1935 and has since then extended its range ever more southward within North America.

The wingspan is 30–38 mm. Adults are on wing from May to July in one generation.

The larvae mainly feed on Vaccinium uliginosum and Vaccinium myrtillus, but has also been recorded on Salix caprea and Sorbusa ucuparia.
