Alder leaf beetle

The Alder leaf beetle (Agelastica alni) is a species in the genus Agelastica. It is currently classified as Least Concern on the IUCN Red List. Typically found in virtually all terrestrial and freshwater habitats.

Lémur Brun

The common brown lemur (<em>Eulemur fulvus</em>) is a medium-sized primate endemic to Madagascar, typically inhabiting diverse terrestrial and aquatic environments including tropical moist forests. This species is classified as Vulnerable on the IUCN Red List, reflecting significant population declines driven primarily by habitat loss and fragmentation resulting from deforestation and land conversion across its native range. As a member of the family Lemuridae, the common brown lemur is characterized by its brown to gray fur, pale face patches, and social group-living behavior. The species is typically diurnal and cathemeral, meaning it may be active during both day and night depending on season and conditions. It often feeds on fruits, leaves, flowers, and invertebrates, making it an important seed disperser in Malagasy forest ecosystems. The common brown lemur typically lives in social groups ranging in size from a few individuals to over a dozen animals. Biological traits of this species remain poorly documented in the scientific literature.
