A restricted cranberry-field bug holds one of the last populations of this species east of Storebælt.

This animal being paler than most of the others seen today, ca. 25.

Bogs near Skørping.
A pale individual that could easily fool me to think it was a B. selene [Brunlig Perlemorsommerfugl]. But aquilonaris has the black spots in the diskal area of the upper forewing lined up in bands rather than single spots, which can be seen here. And even though both can fly in forest habitat only aquilonaris would fly in a true bog habitat filled with cranberry - I guess...
