Predaceous Diving Beetle - Graphoderus liberus
Edmonton, Alberta, Canada
May 23, 2005
Size: ~ 10 mm
This beetle was collected at Devonian Botanic Garden just west of Edmonton, then brought back to the lab and photographed in a special tank. Habitat was in the emergent vegetation at the edge of a shallow pond. Any help getting it to genus or species would be appreciated.

Graphoderus liberus
That should be Graphoderus liberus, not Rhantus. Probably uncommon in this region

Yes, a Rhantus
But lack of dorsal view and detail prevents me from making any conclusive id beyond that for now.
