Recommendation: Arizona beetles, bugs, & birds blog
We live in the midst of the Tucson Mountains Regional Park west of town, surrounded by an abundance of Sonoran desert flora and fauna. My wife Ann, works from home and sees a continuing parade of critters coming down for a drink or shady place to hang out. One of her favorite online resources is Margarethe Brummermann's blog "Arizona: Beetles, Bugs, Birds, and More," subtitled "Adventures and observations of a biologist and watercolor painter in Arizona's deserts and mountains."
Her photos are gorgeous and there are numerous links to help you figure out what you are looking at in your back yard or morning hike.
