Morley’s Final Catalogue: Still apparently rare here; local in Britain. Taken at Felixstow in 1903 by Gibbs (EMM. 1904, 80); by beating hedges in Gorleston lanes during August 1933 (Mly); at Swefling by the Revd. R. Peek; and Brandon by Barrett.
Recent Status: A common species across Suffolk.
Life Style: The single brooded species flies at night during summer and will come to light. The black larvae feed on Blackthorn from a web spun over twigs. They have also been found on Hawthorn, Cotoneaster and Sorbus species. They overwinter in the webbing where they pupate in early summer.
Identification: Acrobasis suavella is similar to A. advenella. Both have a sub-basal line and pre median line that enclose an area on the dorsal half of the forewing. This is less well defined in A. suavella where the white sub-basal line is weak. The red scales, mixed with black and white, enclosed by this area cover the basal area of the wing and partly on the thorax but do not reach the head which is grey. A. suavella is a little larger and broader winged than A. advenella.Recorded in 42 (72%) of 58 10k Squares.
