I saw lots of black bees last year on my white coneflowers, and these little critters were lightning fast. They didn't stay anywhere longer than a few seconds.
It's strange how I've not noticed them before, or last year or remember if they were in my yard at all! We always had bumble bees, honey bees, yellow jackets, and wasps, but a complete black bee was new to me.
This little black bee collected a full leg of pollen. Just like their other cousin bees, they are always very busy..
With coarse rice to eat, with water to drink, and my bended arm for a pillow - I have still joy in the midst of these things. Riches and honors acquired by unrighteousness are to me as a floating cloud.~~~Confucius~~~
