I'm certainly tending to the view that professional help is needed! They seem so much more agressive than normal bees though. I've just been out trying to get a better look at one to help identification but I'm too nervous to agitate the bush so its not easy. They are very dark and look larger than normal honey bees but not wasp shaped. There are fuschias out in flower next to that bush but only normal honey bees and bumble bees on that.
