The Bees in Your Backyard

Honeybees can be managed in hives because in nature they congregate in tree cavities, but 70 percent of wild bees nest in the ground, often as solitary insects or as a congregation of loners: Think of an apartment building full of singles. Maybe as many as a third of bees evolved to feed off a given flower or flower family. The others are generalists and will devour whatever nectar and pollen is around. - Adrian Higgins
