From my kitchen window I can view our fishpond. I have observed many wasps and bees that come to drink in the pond. I made a video of the wasps that visit my pond. I am fairly certain that these wasps are paper wasps. However, I have also noticed a much larger wasp - we called them hornets when we were children - which I think is a potter wasp.
I think that the paper wasps have their nest somewhere in the grape vine because they are coming and going from that area of the garden. I haven't been able to spot their nest as yet. Paper wasps will sting if their nest is being attacked. I have no idea where the potter wasps are coming from, they appear one at a time, whereas I think that there must be more than one paper wasp nest as they appear in large numbers and apparently there are around 20 wasps to one colony.
I must research as to whether wasps are a useful garden insect as potter wasps paralyse caterpillars and put them in their little houses made of mud, they then lay eggs on the caterpillar and when the eggs hatch the larval wasps feed on the caterpillar.
