Common Cusimanse

<em>Crossarchus obscurus</em>, commonly known as the common cusimanse or long-nosed cusimanse, is a small social mongoose in the family Herpestidae. This species is native to the rainforests and dense tropical forests of West and Central Africa. Common cusimanses are highly social animals that typically live in family groups and forage cooperatively on the forest floor, using their elongated, flexible snouts to root through leaf litter and soil in search of invertebrates, small vertebrates, and fallen fruits. They communicate through a variety of vocalizations and are known to mob and harass potential predators. The species is diurnal and terrestrial, sheltering in burrows or dense vegetation at night. Common cusimanses are assessed as Least Concern by the IUCN, with populations considered stable across their range. Biological traits such as lifespan and body measurements remain poorly documented in the scientific literature.

Common oak midget

<em>Phyllonorycter quercifoliella</em>, the common oak midget, is a very small moth in the family Gracillariidae. This leaf-mining species lays its eggs on oak leaves, and the larvae feed by mining within the leaf tissue, creating characteristic blotch or tentiform mines visible on the upper or lower surfaces of leaves. <em>Phyllonorycter quercifoliella</em> typically inhabits deciduous woodland, forest margins, parks, and hedgerows where oak trees (Quercus species) are present. Its geographic range spans temperate Europe, with documented occurrences in multiple countries including Belgium, Denmark, Norway, and Sweden, among others. The species is currently assessed as Least Concern by the IUCN. Biological traits such as lifespan, body size, and diet remain poorly documented at a formal population level for this species, though larval leaf-mining behavior on oak is well documented. Adults are tiny with narrow, patterned wings typical of the Gracillariidae family. <em>Phyllonorycter quercifoliella</em> is one of several oak-associated Gracillariid moths in Europe and forms part of the complex invertebrate community inhabiting European oak woodland ecosystems.
