Norfolk status Notocelia roborana is usually larger than N. trimaculana and roughly the same size as N. rosaecolana.
The male differs from N. rosaecolana by the dark brown basal patch extending along the costal fold, which is diagnostic. Females are more problematical but should be separable by the costal strigulae being broader and less oblique.
Individual variation occurs in some populations so care is advised.
Fairly common and well distributed through the British Isles in hedgerows, chalk downs and open woodland, especially where dog rose occurs, coastal cliffs and sandhills where it is sometimes plentiful on burnet rose. widespread and fairly common in Norfolk. Larvae feed on Wild Rose and Cultivated Rose.
