Given highly divergent physiology and population dynamics, terrestrial invertebrates may exhibit responses to climate change that vary greatly from those predicted for many vertebrates. Additionally, variation in abiotic factors associated with climate change (temperature, moisture, ambient CO2 levels) may inconsistently impact taxonomic groups of terrestrial invertebrates due to differences in physiological mechanisms to handle temperature and moisture fluctuations (Bradshaw and Holzapfel 2010, Bale et al. 2002). This report focuses on Lepidoptera (butterflies and moths) that feed on temperate forest trees, holometabolous insects that experience drastic anatomical and physiological change during metamorphosis.
