I'm not sure about number of pollinator insects in terms of population, but in the southeast for example, the southeastern blueberry bee (https://en.wikipedia.org/wiki/Habropoda_laboriosa https://en.wikipedia.org/wiki/Habropoda_laboriosa) pollinates blueberries through buzz pollination. I believe even commercial blueberry operations rely on this pollinator, as blueberries are native to North America and those bees are its primary pollinators.
