Yeah, this is a Giant Water Bug.

Often confused for a cockroach or a beetle, but they're not.

I've caught them a number of times as well, back in '04 I was curious what they were so I searched them out with my own pictures:

Sorry, I should have also mentioned that they can deliver a seriously nasty bite if you scare or threaten them, so be careful.

They are also known as "Toe Biter" - for reasons which become apparent when you have a close look at their piercing mouth parts!

The first one I ran across had those parts buried deep in a 2 1/2'' long dragonfly nymph (which up until then I had thought was the top insect predator in our local lakes) and was busy draining the last of it's enzyme digested innards.

A week later I saw my first predatious diving beetle and realized there are some big, ugly monsters living in our waters! I wonder if they are ever taken by larger trout, or if they would just be more trouble than they are worth?

It was about 8 years ago that I saw my first Predacious Diving Beetle (Tiger Beetle) in the stomach of a large trout and had no idea what it was but saved it and showed it to Brian Chan and he told me. Scary creatures for sure!

I saw one of these guys this weekend fishing a small lake in whistler. My girlfriend and I were shore casting dry flies for small rising rainbows in the late evening after a nice sit down dinner in the village. It was just turning about turning dusk and several bats started coming out and were grabbing insects out of the air. I remarked to my girlfriend, wouldn't it be funny if a bat went after the fly on the water? Not a moment after I had said this three bats in quick succession took diving runs and my small parachute adams. The third one pushed the fly underwater and I thought for sure I'd hooked it, luckily that wasn't the case. Thinking this was a sure sign that I should pack it in, I pulled the fly out of the water with a quick back cast and caught the fly. Only on the rods was back I was sure I had hit something. I motion in the water caught my eye and I saw what looked to be a small black creature flopping round in the water. I thought I must have hit a bat and knocked it into the water. I couldn't reach it right away with my net but I managed to pull it closer to me with a loop of fly line. I netted it and was shocked to find it wasn't a bat but a Giant Water Bug! I put the net down on the dock as my girlfriend asked what was it was, I promptly replied "Honey you're not going to like this one!". I had read this post just prior to heading to whistler, otherwise I would have had no idea what this thing was. You don't really get a sense of how big they are until you have seen one up close.
