Overview

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

The vensterwaterroofkever faces severe population declines primarily due to habitat degradation and loss of suitable aquatic environments. Water pollution from agricultural runoff and urban development has contaminated many of the clean, well-oxygenated water bodies this species requires for reproduction and larval development. Climate change-induced alterations to precipitation patterns and water temperature regimes further threaten the delicate ecological balance of its freshwater habitats.

Threat summary

Habitat

This aquatic beetle inhabits clean, well-oxygenated freshwater environments including ponds, slow-flowing streams, and shallow lake margins with abundant vegetation. It requires stable water levels and high water quality, particularly during breeding season when larvae develop in the sediment and among aquatic plants.

Frequently asked questions

Why is vensterwaterroofkever classified as Endangered?
vensterwaterroofkever is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. The vensterwaterroofkever faces severe population declines primarily due to habitat degradation and loss of suitable aquatic environments. Water pollution from agricultural runoff and urban development has contaminated many of the clean, well-oxygenated water bodies this species requires for reproduction and larval development. Climate change-induced alterations to precipitation patterns and water temperature regimes further threaten the delicate ecological balance of its freshwater habitats.
Where does vensterwaterroofkever live?
vensterwaterroofkever occurs in Åland Islands, Austria, Belarus, Belgium, Canada, and Croatia (plus 20 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to vensterwaterroofkever?
The main threats to vensterwaterroofkever are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
