An extreme rare and very local species in Belgium, recently only known from a handfull of observations in NA after 2004.
Wingspan 15–20 mm. Caution must be taken because this species is similar in appearance to the form brunneana of Acleris variegana but can be distinguished by the presence of an erect scale-tuft in the submedian fold in Acleris variegana and its absence in A.permutana.
The caterpillars feeding in spun shoots and leaves. Hibernates as an egg. The adults are quite elusive by day, but are attracted to light after dark.
The adults fly from late June towards mid-October.
Preferring coastal sanddunes and limestone habitats.
