common horse fly

<em>Haematopota pluvialis</em>, commonly known as the common horse fly, is a blood-feeding dipteran insect in the family Tabanidae. It is classified as Least Concern on the IUCN Red List. The species is recorded from Belgium, Denmark, Norway, and Sweden, with a distribution centered in northwestern Europe, where it typically inhabits moist, vegetated areas near water bodies, woodland margins, and pastures. Female horse flies are well known as ectoparasites of large mammals, while males are primarily nectar feeders. Diet information beyond this general feeding ecology is not available in current species records. Biological traits of this species remain poorly documented in the scientific literature.

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.
