Taxon: Cnephasia asseclana

=Cnephasia interjectana

Authority: ([Denis & Schiffermüller], 1775)

Vernacular: Flax Tortrix

Account: Common in gardens, farmland and other open areas throughout much of the British Isles Distinguished from C. pasiuana by the usually stronger and more variegated forewing pattern with a relatively narrow median fascia. Smaller than C. stephensiana but with similar dark markings so could quite easily be confused with small specimens of that species. Can be determined with certainty only by dissection of the genitalia. Larva polyphagous on various herbaceous plants, living within a spun or rolled leaf.
