About

An active, underwater predator, the Saucer bug spends its time around the bottom of weedy, muddy ponds hunting invertebrates, tadpoles and small fish. Adults have sharp, pincer-like legs, which enable them to catch their prey. They then stab it with their 'beak', injecting digestive enzymes into the wound and sucking out the contents of the body.

What to look for

The Saucer bug has an oval, yellowy-brown body, with large eyes and a pair of sharp, pincer-like legs at the front. It has a silvery underside, created by the air bubble it holds there while underwater. It can be distinguished from water beetle species by its overlapping wings and piercing mouthparts, rather than biting jaws.

Where to find

Found in England and Wales.
