common grey sea slug

<em>Aeolidia papillosa</em>, commonly known as the common grey sea slug, is a nudibranch mollusc belonging to the genus Aeolidia within the family Aeolidiidae. Despite the species name referencing terrestrial and aquatic habitats including forests and freshwater, <em>Aeolidia papillosa</em> is primarily a marine organism. Its range includes Belgium, Chile, Denmark, Norway, and Sweden, indicating a distribution across the North Atlantic and into South American waters. Common grey sea slug is assessed as Least Concern on the IUCN Red List. The species is typically found in intertidal and subtidal zones, where it preys on sea anemones and stores stinging cells from its prey in its dorsal cerata for defense. Biological traits of this species remain poorly documented in the scientific literature.

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.
