This 2 June 2020 video from Britain says about itself:
Simon King introduces the Interactive Solitary Bee Hive demonstrating its ability to reveal the hidden world of solitary bees. The Interactive Solitary Bee House provides a much-needed resource for solitary bees who can struggle to find somewhere to lay their eggs. Encourage them into your garden by either making your own Bee House or buying a ready-made one and placing it on a south-facing wall where it gets maximum sun in your garden.
