Common Eastern Fleabane

<em>Erigeron strigosus</em>, the common eastern fleabane, is a native North American wildflower in the family Asteraceae, currently not evaluated by the IUCN Red List. The species is distributed across Asia, Europe, and North America, where it typically colonizes diverse terrestrial tropical to temperate habitats, including disturbed roadsides, old fields, forest edges, meadows, and grasslands. As an annual or biennial herb, <em>Erigeron strigosus</em> typically produces numerous small, daisy-like flower heads with white to pale lavender ray florets surrounding a yellow central disc. The species blooms from late spring through summer and is well adapted to open, disturbed environments, making it a common colonizer of agricultural margins, vacant lots, and second-growth vegetation. Its achene fruits, each tipped with a pappus of bristles, are wind-dispersed, facilitating rapid colonization of suitable habitats. Common eastern fleabane provides nectar and pollen resources for a variety of generalist pollinators, including small bees, wasps, flies, and butterflies. In traditional folk medicine, various parts of fleabane species have been used by Indigenous peoples for diverse purposes. Biological traits of this species remain poorly documented in the scientific literature.

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.
