Colonial bentgrass

<em>Agrostis capillaris</em>, colonial bentgrass, is a perennial grass in the family Poaceae with an extensive native range across Europe and naturalised populations in North America, South America, and Oceania, including Australia and New Zealand. This species is highly adaptable, colonising tropical and subtropical moist broadleaf forests, temperate grasslands, disturbed soils, roadsides, and cultivated landscapes within the Neotropical realm. It is assessed as Least Concern by the IUCN. Colonial bentgrass is a fine-leaved, low-growing species often used in lawn and sports turf applications due to its tolerance for close mowing and its capacity to form dense, even swards. Its panicle inflorescences bear numerous small spikelets on delicate, hair-like branches, giving the species a feathery appearance when in flower. In its naturalised range, <em>Agrostis capillaris</em> can become invasive, competing with native grass species in acid grasslands and open heathlands. The species tolerates acidic and nutrient-poor soils, attributes that contribute to its widespread persistence in degraded landscapes. Biological traits of this species remain poorly documented in the scientific literature.

Common Birch Bell

The common birch bell (<em>Epinotia immundana</em>) is a small tortricid moth found in terrestrial and freshwater habitats across temperate Europe. Its confirmed range includes Belgium, Denmark, Norway, and Sweden. The species is classified as Least Concern on the IUCN Red List. As the common name suggests, <em>Epinotia immundana</em> is closely associated with birch trees, where its larvae typically feed on birch foliage and developing buds. The adult moths are small and cryptically patterned, making them difficult to detect at rest on bark or leaf litter. Like other members of the family Tortricidae, the larvae often roll or tie leaves together to create protective shelters during feeding. The species typically completes one or more generations per year, depending on local climate conditions. Biological traits of this species remain poorly documented in the scientific literature.
