Morley’s Final Catalogue: Observed nowhere but at Nayland, on our south border, in 1896 (C. A. Pye),
Recent Status: A common late summer species in Suffolk. In respect of Morley’s comments. A. laterana was referred to as A. comparana but may also be included in part under a variant var. latifasciana under Acleris schalleriana. At the same time there may well be nomenclature confusion with A. comariana.
Life Style: A night flying single brooded Acleris. Overwintering as an ovum. The larvae feed from spun leaves and flowers on a variety of deciduous trees and shrubs.
Identification: The species is highly variable. The ground colour ranges from white through shades of yellow, orange and reddish brown or grey with or without dark speckling. The dark dash/scale tuft near the base of the dorsum is consistent. The costal blotch may be orange/brown through to black and extend over much of the wing except for a narrow terminal strip and the basal third. There can also be dark shading on the head and thorax that extends into the basal part of the wing. Some forms are similar to A. comariana but A. laterana is larger at 15 to 20 mm. Some forms are similar to A. schalleriana but that species has broader shoulders and relatively longer narrower wings. More Info
