Distribution

This species can be found in Great Britain, the Benelux, France, Germany, Denmark, Switzerland, Austria, Italy, the Czech Republic, Slovenia, Croatia, Bosnia and Herzegovina, Hungary, Romania and Greece, as well as Turkey and Russia.[3]

Habitat

These moths prefer hedgerows, woodland rides and margins, where hawthorn, oak and other host plants are present, but also it can be found on coastal salt marshes.[4]

Description

Adults are sexually dimorphic. The wingspan reach 11–14 mm in females, while males have less distinct forewing markings and they are larger, as their wingspan reach 14–16 mm. Forewings are grey-brown, with darker brown transversal markings.[5][6] This species is quite similar to moths belonging to genus Cnephasia, but the hedge shade has directly transverse dark brown markings.[6][7]

Biology

Adults are on wing from May to July in one generations per year, flies from dusk onwards and comes to light.[8][9]

The life-history of this species is imperfectly known but larvae have been reared from, and pupa found on, hawthorn (Crataegus species).[9] Larvae have also been reared on Acer and oak (Quercus species).[10] They feed from within a silken tube on the underside of a leaf.[11]
