cloaked pug

The cloaked pug (Eupithecia abietaria) is a geometrid moth in the family Geometridae found across boreal and montane Europe, with populations extending from Scandinavia through the Alps and Carpathians into central Siberia. The adult wingspan measures approximately 20–25 mm, with the intricate grey, white, and dark cross-banded pattern typical of pug moths providing superb camouflage against spruce bark and lichen-covered surfaces. The species is closely associated with Norway spruce (Picea abies) and related conifers, whose developing cones serve as the principal larval foodplant. Larvae feed within the scales of ripening cones, making detection and study challenging. Adults fly in a single generation from June to August, active at night and attracted to light. The cloaked pug is characteristic of mature boreal coniferous forest and montane spruce woodland, habitats that have declined in extent across parts of Central Europe due to conversion to plantation forestry and changing forest management practices. Its conservation depends on the maintenance of naturally structured boreal and subalpine forests with abundant cone-bearing conifers.

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.
