Apotomis betuletana
Birch Marble

(Haworth, 1811)1093 / 49.150

Morley’s Final Catalogue: Much overlooked by us, and doubtless not uncommon. Blythburgh Wood (D); Bentley Woods in August 1895, in the utmost profusion at light beside Fritton Lake in 1932-4; Tuddenham in 1902, and at dusk at Barton Mills in 1933 (Mly). Bentley, Sutton Heath and Minsmere in 1933-5 (Whit).

Recent Status: Frequent in areas with birch.

Life Style: Single brooded flying by night and coming to light from June to September. The larvae feed on Betula from leaf spinnings and 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
