KillerPix📷Contest #38 bees - mining bee at work

This is my contribution to @killerwhale #killerpix photography contest
I made these in my garden this morning with my Sony A7II + reversed rokkkor 28mm 3.5 + 16mm extension tube to get a bit closer to the bee.
This is a mining bee that lives solitary and not in a swarm, the dig holes in the ground lay eggs and add some food for the larves.

Here you can see the bee harvesting food from the campanula flowers,
