Sometimes known more commonly as the Saucer Bug or Water Bug, Ilyocoris cimicoides is a widespread aquatic species, across the southern half of the UK.
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', inject digestive enzymes and suck out the contents of the body.
The Saucer Bug has an oval, yellowy-brown body, with large eyes and a pair of sharp, pincer-like legs at the front. It can be distinguished from water beetles by its overlapping wings and piercing mouthparts, rather than biting jaws. It can inflict a painful bite.
