Species showcase – Great Diving Beetle

During a recent service on an ecosystem pond we encountered this little chap; the Great diving beetle. The Great diving beetle is one of our largest beetles and can be distinguished by its blackish-green colour, with a yellow border around the thorax and wing cases.

They are often found in slow-moving water and ponds where they are voracious predators, feeding on tadpoles and small invertebrates. Adult Great diving beetles can be spotted poking the tips of their abdomens out of the surface of the water in order to replenish the air supply stored beneath their wing cases.
