Common Flower Fly

<em>Syrphus ribesii</em> is a hoverfly in the family Syrphidae, order Diptera, commonly known as the common flower fly. This species is among the most frequently encountered hoverflies in its range and serves an important ecological role as a pollinator of flowering plants. The species is classified as Least Concern on the IUCN Red List. <em>Syrphus ribesii</em> is distributed across Europe and the United States, typically inhabiting gardens, hedgerows, woodland edges, and meadows where flowering plants are abundant. Adults are characterized by yellow and black banded abdomens that mimic the appearance of wasps or bees, providing protection from predators through Batesian mimicry. Adults feed on nectar and pollen, while larvae are predatory, feeding on soft-bodied insects such as aphids and thereby providing a natural pest control service in gardens and agricultural settings. The species is migratory in parts of its range. 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.
