Water Scavenger Beetle - Helophorus grandis
Hanlon Creek, Guelph, Wellington, Ontario, Canada
April 19, 2010
Size: 7.0 mm
A very large Helophorus, scooped from puddle. At this size, I'm reasonably certain that it is H. grandis.

Thanks Tim!
This one stood out for sure. I had based my initial ID from pg. 300 of Marshall (2006).
