Jefferson County, Washington, USA September 22, 2011
After never seeing any insects around these holes in a sandy bluff on a saltwater shoreline, today there were many solitary bees flying in, around, and out of them. yellow-jacket sized, with strong stripes on their relatively hairless (as far as I could tell through my binoculars watching them 20 feet up the bluff) abdomen. They were too far up the bluff to get a photo of them, but here are some photos of the bluff with all the holes.
