British Columbia has generally had a good year for bees.
In some areas wasps have done very well, too. I've seen a recent report
that wasps have consumed 30 % of a commercial grape crop (there was an
abundance of caterpillars in early summer, and weather conditions caused
some of the grapes to split).
In my northern area, wasps have been patchy and generally hardly
noticeable until the last 3 weeks. I don't know of any analysis finding
a relationship between wasp populations and their food source, but I
would expect it.
