This is a valiant wild bee trying to build a nest in the middle of the sidewalk. It probably won't be successful. 

I'm creating a sandarium in a quiet corner of my garden to help them with a tiny bit of habitat.

Providing a sandarium in your garden is a great way to support wild bees, offering them a safer and more suitable environment to build their nests. Nature thanks to you🍄 🍄
