Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Dytiscus dimidiatus faces severe population declines due to widespread habitat degradation and loss of suitable aquatic environments. The species is particularly vulnerable to water pollution, eutrophication, and drainage of wetlands for agricultural and urban development, which have significantly reduced the availability of clean, well-oxygenated water bodies essential for its survival.
Key Facts
Habitat & Distribution
This diving beetle inhabits clean, well-oxygenated freshwater environments including ponds, lakes, slow-flowing streams, and marshes with abundant aquatic vegetation. The species requires stable water bodies with good water quality and minimal pollution, typically in lowland areas with rich invertebrate prey communities.
