Species Profile
Bagous lutosus is a small weevil species belonging to the aquatic weevil genus Bagous, characterized by its brownish coloration and specialized adaptations for semi-aquatic life. These beetles typically measure 2-4mm in length and play an important ecological role as herbivores of aquatic and semi-aquatic plants, particularly in wetland ecosystems.
Bagous lutosus 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.
