Flowering Rush Weevil
Bagous nodulosus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Flowering Rush Weevil faces severe habitat loss as its host plant, flowering rush (Butomus umbellatus), experiences widespread decline across European wetlands due to drainage, pollution, and agricultural intensification. Water quality degradation from agricultural runoff and urban development further threatens the aquatic and semi-aquatic environments this specialized weevil requires. Climate change poses additional risks through altered precipitation patterns and increased frequency of extreme weather events that can disrupt the delicate wetland ecosystems upon which both the weevil and its host plant depend.
Habitat
The Flowering Rush Weevil inhabits freshwater wetlands, shallow lake margins, and slow-flowing rivers where its host plant flowering rush grows. It requires clean, nutrient-rich aquatic environments with stable water levels and emergent vegetation zones.
