How can people help

Many of our commonly overlooked insects are actually important nutrient-recyclers and pest controllers in the habitats they live in. Minibeasts, such as the Rhinoceros Beetle, can be encouraged into the garden by the provision of logs, stone piles and compost heaps for them to hide, feed and breed in. 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.
