Great Diving Beetle

I had taken the 50D out in the garden as I had spotted a Sparrowhawk fly past. No sign of the bird so I checked the pond for signs of life. What a surprise. There basking on a lily pad in the glorious sunshine was a Great Diving Beetle. It stayed long enough to get a few shots before diving to the bottom. That was the first indication that there were any diving beetles in my garden pond. I never know what is going to turn up next and often wonder how the various creatures arrive in the first place.
