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.

Onca

O maior felino das Américas, atingindo até 100 kg com corpo robusto e musculoso e pelagem com padrão de rosetas característico. Encontrado do México até a América do Sul, com populações mais expressivas na Amazônia e no Pantanal. Nadadores poderosos e predadores de topo, os jaguares desempenham papel fundamental na regulação das populações de presas. Classificado como Quase Ameaçado, com sua área de ocorrência diminuindo devido ao desmatamento.
