common greasewort

<em>Aneura pinguis</em>, commonly known as common greasewort, is a liverwort belonging to the genus Aneura within the family Aneuraceae. This cryptogamic plant inhabits ecosystems across Asia, Europe, and North America, thriving in moist or waterlogged environments. Its range encompasses Taiwan in Asia, six European countries, the United States in North America, and Brazil and Colombia in South America, indicating a broad geographic distribution across multiple continents. Common greasewort is assessed as Least Concern on the IUCN Red List. The species typically forms flat, ribbon-like thalli in damp habitats such as stream banks, wet rocks, and boggy ground. Biological traits of this species remain poorly documented in the scientific literature.

Common Plain Neb

<em>Monochroa tenebrella</em>, the common plain neb, is a small moth in the family Gelechiidae, a large and taxonomically complex family of micromoths. It is a nondescript, grey-brown species with narrow forewings typical of the gelechiid body plan, making field identification challenging without close examination. The species is typically associated with wetland and riparian habitats, where its larval host plants are found, and adults are usually encountered in late spring and early summer. <em>Monochroa tenebrella</em> is distributed across northern Europe, with confirmed records from Belgium, Denmark, Norway, and Sweden, suggesting a preference for temperate Atlantic and continental European climates. It is assessed as Least Concern on the IUCN Red List, reflecting an absence of major known threats at the population level. Biological traits such as average adult lifespan, wingspan measurements beyond general range estimates, larval host plant associations, and detailed dietary data remain poorly documented in the scientific literature. Like many micromoths, the species is understudied relative to larger Lepidoptera, and its ecology, population dynamics, and responses to habitat change are not well characterised. Continued recording by amateur lepidopterists is important for monitoring its distribution and status.
