Scientific name: Cassida viridis
When threatened, the Green tortoise beetle acts just like a tortoise, pulling its feet and antennae in and hunkering down, gripping the leaf it is on as tightly as possible. Look for it on White Dead-nettle in gardens and hedgerows.

About

The Green tortoise beetle is one of a group of several closely related beetles. It feeds on White dead-nettle, Hedge Woundwort and Water Mint, and is often found in gardens. When disturbed, the adults behave just like tortoises, retracting their antennae and feet, and pulling their 'shell' tight down around them as they grip tightly on to the leaf they are on.

What to look for

The Green tortoise beetle is round, flattened and lime green. Tortoise beetles are easy to identify as a group, but there are several closely related species that are very difficult to tell apart; the Green tortoise beetle is entirely green and generally lacks the markings of other species.

Where to find

Widespread in England and Wales, rarer in Scotland.

Habitats

Did you know?

The spiny larvae of the Green tortoise beetle hold a 'coat' of cast skins and droppings on their backs to camouflage themselves and deter predators.
