Graph*oderus occi*dentalis - Acilius
Sunapee, New Hampshire, USA
April 18, 2008

first, welcome to BugGuide!

with water beetles, most of the critical parts for ID are located on the underside, specially between each pair of legs.

No.
The identification, I am quite certain, is incorrect. I wish I could offer an alternative this instant, but I can't. Moving to family page for now.
