    Hi Patrick-

    Reasonable guess, but It isn't a waterboatman, nor is it of family Corixidae.

    It's not the giant water beetle, is it?

    Also I thought backswimmers were a member of the waterboatman family.

    hi zen leecher-

    It is not a giant water beetle, and Backswimmers are not in family Corixidae. However it is in fact a Backswimmer.

    Hemiptera; Heteroptera; Notonectidae. Does this fill in the missing information?

    I am researching that there are 2 or 3 genera in North America.

    Distinguishing features appear to be size and antenna segments.

    So I will guess it is either Buenoa or Notonecta. The latter being larger.

    I will call it Notonecta (50% chance?)
