Species Profile
Bagous brevis is a small weevil species measuring 2-3mm in length with a distinctive elongated rostrum and dark brown to black coloration. This aquatic weevil plays a crucial ecological role as both herbivore and prey species, feeding on submerged aquatic plants while serving as food for fish and other aquatic invertebrates.
Bagous brevis faces significant threats from habitat degradation and loss of wetland ecosystems across its range. The species' specialized dependence on aquatic plants makes it particularly vulnerable to water pollution, drainage of wetlands, and changes in water quality that affect its host plants.
Key Facts
