Butterfly systematics is experiencing a renaissance. Its renewed vigor is due to the widespread realization that robust phylogenies and objective species delimitations are crucial for comparative investigations in biology and conservation, as well as to the recent development of easily applied techniques for assaying DNA sequences and other molecular variation (Hillis et al. 1996). Molecular techniques have allowed a surge in systematic investigations ranging in scope from surveys of gene flow among intraspecific populations to examinations of deep phylogenetic divergences (eg, Brower 1994a; Sperling and Harrison 1994; Weller and Pashley 1995). However, the advantages of molecular investigations may also be a source of fundamental problems. A student can usually produce reliable molecular datasets in a matter of months, whereas it often takes years to train a researcher who is proficient at morphological …
