The Great Silver Diving Beetle

Cycled down to the Avalon Marshes centre and enjoyed some pond dipping with the boys. There were juvenile newts, frogs, boatmen and lots of beetles in the water. I was surprised at the size of the enormous Great Silver Water Beetles as I had mistakenly thought that the handsome Great Diving Beetle was our largest water beetle, but apparently not. 

We also learnt that you can tell the male beetles from the females as the males have a small flap at the front of their front legs that the females don't have. Beautiful and impressive insects.
