Tidying the garden often uncovers an interesting selection of beetles that live in lawn edges, compost heaps or lurk under logs, as they're well adapted to pushing through root thatch and getting into tight spaces.

Most are useful predators of other invertebrates like bugs, aphids, springtails and maggots. They can be picked up carefully between finger and thumb if you want to relocate them to a nature area. Some larger beetles will try to nip with their jaws, but they can't pierce human skin.

To encourage them and other beneficial insects to take up residence in your garden, be sure to create habitats for them such as dead wood stacks, compost heaps and bug boxes.
