The two charities are calling on gardeners to create habitats for these important but often overlooked insects which are a vital part of every healthy garden.
Providing a patch for beetles, including ladybirds, ground beetles and rose chafers, is a great way to encourage balance in the garden and boost biodiversity, with many species under threat from habitat loss, pesticide use and climate change.
The UK has more than 4,000 beetle species and, although a handful may eat plants, many are predators, pollinators and decomposers, feeding both the soil and larger garden visitors such as birds and hedgehogs.
