Leek Flowers With Solitary Bee

There are a lot of little solitary bees about at present. This one is about 7mm, but they range from about 2mm to 10mm. The smallest are barely noticeable, but sometimes if I take a macro of a very tiny insect I will see the distinctive bee shape. I think this one is a Leioproctus,  of the family Colletidae.

I love the leek flowers. They are bouncy pompoms of purple or white, and the tiny individual flowers are so quaint. Any leeks I have left over at the end of winter I transplant for clumps of flowers.
