mandelblommevivel

Bagous diglyptus

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Bagous diglyptus faces significant pressure from wetland habitat degradation and loss throughout its limited range in Scandinavia. Agricultural intensification and urban development have reduced the availability of suitable aquatic plant communities that this specialized weevil depends upon for reproduction. Water pollution and eutrophication further compromise the quality of remaining wetland habitats, while climate change may alter the distribution and abundance of its host plants.

Threat summary

Habitat

This specialized weevil inhabits freshwater wetlands, marshes, and shallow lake margins where it depends on specific aquatic and semi-aquatic plant species for feeding and reproduction. The species requires clean, nutrient-balanced water systems with established vegetation communities typical of northern European wetland ecosystems.
