Spatial and temporal refugia for an insect population declining due to climate change

Abstract Insect declines have been reported worldwide, although the particular causes of the declines may be complex and are poorly understood. Meadow spittlebugs were one of the most abundant insects in the coastal prairie along the California coast 40 yr ago but have largely disappeared. Evidence...
