Morley’s Final Catalogue: Occurs sparingly among birch in Bentley Woods in June and July 1901 (Pyett), July 1902 (Gbs) and 1934-5, as well as on Sutton Heath (Whit).
Recent Status: A common species where Birch grows.
Life Style: A single brooded Apotomis, possibly with a second late summer brood. Flies at night and comes to light. The larvae feed from spun leaves of Betula species . They pupate in the larval habitation.
Identification: There are three similar Apotomis species. A. betuletana, A. capreana and A. turbidana. They have the basal three fifths of the wing dark with marking intensity varying. The distal two fifth is pale with grey shaded transverse fasciae. All may have small black dots in the fasciae around mid termen. The posterior edge of the dark area in A. betuletana is straighter so that it does not reach so far back along the costa as in A. capreana or A. turbidana. The central pale deviation into the dark area is also less pronounced in A. betuletana. A. betuletana and A. capreana both can have light ochreous clouding in the pale area. A. turbidana is a more black and white coloured species with a prominent long white splash centrally in the basal half and commonly also on the costa. More Info
