You mistake your backyard for the entire country. I hope the Hawaiian population is doing well, cuz they may have to repopulate both coasts. The Mystery of the Missing Monarch Butterflies Sharol Nelson-Embry, East Bay Regional Park District \| January 17, 2014 Overwintering monarch butterflies return year after year to California groves. Photo taken in Pacific Grove, CA by agunther / Wikimedia Commons. Just two years ago, 4,188 monarch butterflies at Ardenwood Historic Farm in Fremont clustered in dense groupings on their favorite eucalyptus trees. On sunny days, they fluttered and basked, flashing their orange and black wings to the delight of thousands of people who came to view the seasonal wonder. This year, though, Ardenwood naturalist Mindy Castle reported that after a good showing of about 1,000 butterflies in November, the cold snap in December sent most of them fluttering to parts unknown. Only about 30 or 40 monarchs remain, most of them abandoned their Ardenwood overwintering site. The unexpected dispersal from the Ardenwood site, coupled with the unrelated New York Times article which reported the late arrival and smaller numbers of eastern monarchs migrating to Mexico underlines scientists concerns about the overall decline of the North American monarch population. For over a decade, the Xerces Society annual Thanksgiving Monarch Count at overwintering sites in California has revealed a greater than 80 percent population decline across most sites with some sites faring significantly worse. For example, at Natural Bridges State Beach near Santa Cruz, the number of butterflies gathering each winter dropped from an estimated 120,000 in 1997 to just 500 in 2012.” blogs.kqed.org
