Ynghylch

The red-and-black froghopper is one of our largest homopterans - a group of bugs that also includes aphids, leafhoppers and treehoppers. They are found in a wide variety of wooded and open habitats, often on the stems or leaves of low-growing plants. The adults feed by sucking juices out of grasses and other plants. The young froghoppers, known as nymphs, are rarely seen as they feed on underground roots.

What to look for

An unmistakeable bug. Completely glossy black apart from the red markings across the back.

Where to find

Common and widespread in mainland England and Wales

Red-and-black froghoppers have wings and are strong fliers, but you're just as likely to see them moving around with powerful leaps. Their back legs can fully extend in under a millisecond, springing them into the air.
