Common Field Grasshopper

The Common Field Grasshopper (<em>Chorthippus brunneus</em>) is an orthopteran insect belonging to the genus Chorthippus within the family Acrididae. It is one of the most frequently encountered grasshoppers in northern and western Europe, typically inhabiting dry, open areas such as grasslands, heathlands, roadsides, and disturbed ground. The species is often found in virtually all terrestrial and freshwater habitats across its range. Geographically, <em>Chorthippus brunneus</em> is distributed across Belgium, Denmark, Luxembourg, Norway, and Sweden, among other European countries. The species is assessed as Least Concern on the IUCN Red List. Adults are typically brown to grey in colouration with variable patterning, and males often produce a distinctive short, chirping song used in courtship. As a herbivore, this grasshopper typically feeds on grasses and other low-growing vegetation. Biological traits including average lifespan and body dimensions remain poorly documented in the scientific literature, though adults in temperate regions typically appear from mid-summer through autumn.

Eurasian beaver

Eurasian beaver (Castor fiber) is classified as Vulnerable (VU) on the IUCN Red List. Facing a high risk of endangerment in the wild, with declining populations and increasing habitat pressure.
