Offers plenty of choice for different insects, and makes a special feature in your garden. We know already that insects are in decline, help them have somewhere to shelter and complete their life-cycles. The more insects, the more food for birds and other creatures so desperately in need right now!
As well as many other insects, this helpful habitat is great for solitary bees that lay their eggs in tunnels. Watch them come and go on sunny days, building cells for their eggs in the holes using mud and pieces of leaf.
Where in your garden? Choose a sunny position, preferably south-facing, with pollinator-friendly flowers and a source of wet mud in your garden to make life easier for Mason Bees.
