From the publisher:
Bees, wasps, butterflies, moths, flies, and some beetles pollinate more than 70 percent of flowering plants, but North America's native pollinators face multiple threats to their health and habitat. The Xerces Society offers a complete action plan for protecting these industrious animals by providing flowering habitat and nesting sites.
