A lawn bee, Andrena fulva, butt-uppards, works away making a little nest tunnel. I can sit and watch stuff like this for hours. Sometimes it’s fun just to sit in the garden, in the sun, and see what goes on all around you.
Go try it. You’ll be amazed what you find.
If you see an interesting tiny dude, take a picture and look it up on whatsthatbug.com. And don’t kill it!
