Wild bees are beautiful, diverse, and fascinating. Here I've aggregated some of my favorite resources for those who are excited to learn more about wild bees.
Who Are the Pollinators? is a great introduction to the different kinds of insects that pollinate plants.
Wild Bee Conservation describes the biology of wild bees, the threats they face, and how we can help protect them.
The Pollinator Conservation Resource Center includes fact sheets and other publications with region-specific information for the U.S. and Canada on practices to promote pollinator conservation.
Wild Friends, a youth civics education organization focused on wildlife conservation, has worked with students to bring pollinator protection bills to the New Mexico state legislature and to create a Pollinator-Friendly Plant Guide.
Community Science Projects These projects provide great ways that anyone can get involved in collecting valuable data on the status of bees and pollination:
The Great Sunflower Project allows community members to record and submit counts of pollinators visiting plants, with a focus on sunflowers.
Through the Insight Citizen Science app, participants can record sightings of insect pollinators, including bees.
Bumble Bee Watch provides a place to record sightings of bumblebees.
Books
The Bees in Your Backyard (Wilson and Messinger Carril) is a fantastic and very readable book for anyone who wants to learn more about bee biology and identification.
The Solitary Bees (Danforth, Minckley, and Neff) is a definitive guide to the biology, evolution, and conservation of solitary bees, written by experts who have synthesized a vast amount of valuable information.
Other Media
The PolliNation podcast, from Oregon State University Extension Service, profiles "people making bold strides to improve the health of pollinators."
The Insects Unlocked Project of the University of Texas at Austin provides gorgeous photographs of bees and other insects, all in the public domain.
