Really Cool Bug

I found this REALLY COOL bug in our pond outside in the shallows so I scooped it up and identified it. That is a full sized post-it note behind it. A really large bug. I was looking up its name, it's common name is simply large water beetle, its scientific species is belostomatidae. The coloring is beautiful with greens and deep rich browns, unfortunately the picture doesn't do it justice.

My muddy boots, I was wadding through some deep mud.
