I noticed what appear to be sweat bees (see pic below) in my wifes foxglove. I didn't realize that they harvest anything other than sweat, but they were definitely interested in the foxglove and my broccoli. Is this a definitely a sweat bee?
There was also a large completely solid black bee (no pic)in the foxglove and I have no idea what it was. Any idea on what that one could be?
