Cnephasia pasiuana, the meadow shade, is a moth of the family Tortricidae. It was described by Jacob Hübner in 1799. It is found in almost all of Europe.[2] The habitat consists of rough pastures, fens and marshy areas.
The wingspan is 15–19 mm.[3] The forewing pattern varies from pale to dark grey.[4] Meyrick describes it - Antennal cilia of male very short. Thorax crested. Forewings elongate, costa moderately arched, 7 to apex; fuscous, finely irrorated with whitish-ochreous; an angulated fascia at 1/3, central fascia, and apical suffused patch darker, sometimes obsolete. Hindwings pale fuscous, darker terminally, 6 and 7 stalked. The larva yellowish-grey; spots black.[5]
There is one generation per year, with adults on wing from June to July.
The larvae feed on the flowers of various herbaceous plants, primarily Asteraceae species. They have been recorded feeding on Agropyron, Pisum, Brassica, Medicago, Humulus, as well as Ranunculus species. They spin together several petals of their host plant.[6]

Bakkegråvikler (Cnephasia pasiuana) er en sommerfugl som tilhører familien viklere (Tortricidae).
En middelsstor (vingespenn 15-19 millimeter), gråspraglete vikler. Forvingen er lyst gråaktig med tre uregelmessige, mørkere tverrbånd. Noen individer er nesten ensfargede. Bakvingen er lyst gråbrun. Det er vanskelig å skille artene i slekten Cnephasia på ytre utseende.
Larvene lever på blomsterhodene av ulike kurvplanter og også på soleier (Ranunculus spp.). De voksne sommerfuglene flyr i juni-juli, mest på litt fuktige enger.
I nyere tid er arten bare funnet i Østfold i Norge. Den ble vurdert som Nær truet (NT) i den norske rødlisten fra 2015.
