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.

koala

Icónico marsupial del este y sureste de Australia, los koalas pesan hasta 15 kg y pasan hasta 22 horas diarias durmiendo para conservar energía de su dieta de hojas de eucalipto, baja en calorías. Altamente especializados para procesar los compuestos tóxicos del eucalipto que matarían a la mayoría de los demás mamíferos, poseen microbiomas intestinales únicamente adaptados para la desintoxicación. Clasificado como En Peligro en 2022, con poblaciones diezmadas por la enfermedad de clamidia, la deforestación y el cambio climático.
