The Green Tortoise Beetle is one of a group of several closely related beetles. Green Tortoise Beetles feed on White Dead Nettle, Hedge Woundwort and Water Mint, and are often found in gardens. When disturbed, the adults behave just like tortoises, pulling their antennae and feet in and pulling their 'shell' tight down around them as they grip tightly on to the leaf they are on.

How to identify

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 which are very difficult to tell apart.

How can people help

You can encourage minibeasts into your garden by providing logs, stone piles and compost heaps for them to hide, feed and breed in, along with flowers and nettle patches. In turn, other species will be attracted to the garden, as minibeasts are a food source for many animals, including mammals, birds and amphibians, providing a vital link in the food chain. To find out more about encouraging wildlife into your garden, visit our Wild About Gardens website: a joint initiative with the RHS, there's plenty of facts and tips to get you started.
