I'm starting to think it was better when I thought there was only one type of wasp! Here, I've included a wasp that was in the garden today. I can assure that it is the same wasp in both photos. The face shows traits of Norwegian Wasp Dolchivespula norwegica except for there is no sign of a yellow basal segment to the antennae? It does have only 2 thoracic spots however which also suggest Norwegian Wasp. Even though I'm finding it very difficult to clinch the identity of the wasps I'm seeing this year, which is quite frustrating, I have to admire the variation shown by these wasps. In fact I find it hard to pick the variation until the photo is viewed later on. There's no turning back now!
