Over the rustling of wind in the leaves and the rippling of a mountain stream, an unmistakable sound hums through City Creek Canyon on a recent hot afternoon.
It’s the season for yellow jackets, other wasps and bees in the Wasatch Foothills, and they are flying thick, according to cyclists who say they have been swarmed and attacked in City Creek Canyon.
While populations this year aren’t drastically bigger than normal, the insects are noticeably more present in the foothills than they were last year or the year before, said John Wells, watershed operations supervisor for Salt Lake City.
