Common Rose Bell

<em>Notocelia rosaecolana</em>, the common rose bell, is a small tortricid moth in the family Tortricidae, order Lepidoptera. It is distributed across Europe and North America, with documented records from Belgium, Czech Republic, Denmark, France, Germany, Sweden, and the United States. The species is assessed as Least Concern on the IUCN Red List. Rose bell moths in the genus Notocelia are leafrollers whose larvae typically feed on plants in the rose family (Rosaceae), particularly wild roses and related species. <em>Notocelia rosaecolana</em> larvae typically shelter within rolled or tied leaves and feed on foliage, flower buds, and stems of their host plants. Adults are small moths with intricately patterned, mottled brown and grayish forewings that provide excellent camouflage on plant surfaces. Adults are nocturnal and may be attracted to light sources. The species typically produces one generation per year in temperate climates, overwintering in the larval or pupal stage. Biological traits such as precise lifespan, body length, and wing measurements remain poorly documented for this taxon in quantitative studies. The species is considered a minor leafroller pest on cultivated roses in some regions of Europe but is generally managed without dedicated control measures in natural habitats.
