The Brown Diving Beetle (Agabus brunneus) is a species in the genus Agabus. It is currently classified as Extinct on the IUCN Red List. Typically found in virtually all terrestrial and freshwater habitats.

Common Barred Sailor

The common barred sailor (<em>Neptis laeta</em>) is a butterfly belonging to the family Nymphalidae, found in terrestrial and freshwater habitats across its range. It is classified as Least Concern on the IUCN Red List, suggesting the species is not currently facing significant threats to its population. Like other members of the genus <em>Neptis</em>, the common barred sailor is typically characterized by striking dark wings adorned with white banding, giving it a distinctive sailor-like appearance. These butterflies often inhabit forest edges, woodland clearings, and areas with abundant larval host plants. Adults are often observed gliding and sailing on forest paths and sunlit openings, a characteristic flight pattern of the genus. The larvae typically feed on specific host plant species, and the species life cycle includes egg, larval, pupal, and adult stages. Biological traits of this species remain poorly documented in the scientific literature.
