Bradleys andrena females can be distinguished from other small native bees in blueberries by their relatively long face, which can be seen in the photo above (click to enlarge). Although numerous blueberry cultivars are self-fertile and don't need DNA from another blueberry cultivar, some of the blueberry varieties that require cross-pollination in order to bear fruit include the 'Brightwell,' 'Tifblue,' 'Misty,' 'Sharpblue,' 'Chippewa,' 'St. (In fact, cross pollination may lead to a 20% increase in yield!).
