Saucer Bug

Ilyocoris cimicoides


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.

How to identify

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.

How can people help

The Wildlife Trusts manage many wetland nature reserves for the benefit of all kinds of wildlife, from bugs to dragonflies, fish to Otters. But these precious sites are under threat from development, drainage and climate change. You can help by supporting your local Trust and becoming a member; you'll find out about exciting wildlife happenings, events on your doorstep and volunteering opportunities, and be helping local wildlife along the way.
