The hawkmoths (Sphingidae) are a cosmopolitan group of conspicuous moths showing marked variation in both larval and adult life histories. We first test Kitching and Caidouís (2000) classification of the Sphingidae by estimating phylogenetic trees from sequences of the nuclear genes Elongation Factor 1-Alpha (EF1-α) and Dopa Decarboxylase (DDC) for approximately 60 exemplar species plus outgroups. We then use the phylogeny to consider the hypothesized evolutionary correlation between adult feeding and longevity, as inferred from proboscis length, and the number and kinds of hostplants used by larvae.


Species 1: Lepidoptera Sphingidae Manduca sexta (tobacco hornworm)
Species 2: Lepidoptera Sphingidae Hyles lineata (whitelined sphinx)
Keywords: Sphinx moths, Hawk moths
