Moths are observed by using light traps of the “Jalas” model that are equipped with 160W mixed light or 125W Mercury (Hg) vapour bulbs (Jalas, 1960; Söderman, 1994). Traps are run every night from the early spring to the late autumn, typically between April and October. Traps are usually emptied weekly and the moth specimens are identified
