Rural Gardening: Many bees with ground holes, 1 by stillwood

I found this thread today when I was looking where to post a question about bees. We have been away for over a week on vacation. On returning yesterday I found about a dozen bees dead on my kitchen floor in a group and a few others dead scattered around the house. The only thing I can think of as to how they got in (and apparently died from no food or water and the heat in the house) was that the morning I left I brought into the house a potted soft touch holly gotten from Lowes that day. I put the pot down in a larger pot with an inch of water so that it would not dry out and die while I was away. I will take a picture and try to let you see what they look like, but they remind me of the miner bees posted above. Could they have been in the pot and waited until we left to come out - maybe hatched out?
