Metallic green bees are among my favorite insects. I saw these glittering in the autumn sun yesterday as they gathered food from goldenrod flowers. These little native solitary bees nest in the ground, sometimes near each other in aggregations but the females separately supply their brood cells with eggs and provisions of pollen to feed on. There are lots of green bees out there right now getting the last of the year's pollinating done. Click to enlarge.
Here's something Ray Bradbury said about bees in his novel, Dandelion Wine: "Bees do have a smell, you know, and if they don't they should, for their feet are dusted with spices from a million flowers."
