My first time seeing #Deronectes sp. I thought it was a giant Hydroporus 😀 Deronectes is a genus under the tribe #Hydroporini

The brown diving #beetle ( #Agabus brunneus) was a common species in all #stream spots where we were collecting in southern France, but it is a rare and exciting species if you find it in the UK

Caring for diving beetles boosts urban biodiversity | University of Helsinki Ponds in the Helsinki Metropolitan Area serve as habitats for diving beetles. Urban planning and pond maintenance can either degrade or enhance their living conditions.

Over six years, we found a decline in diving #beetle numbers and species richness in #urban #ponds, and the ponds are losing their shared species.
