Molecular and morphological divergence in the butter ̄ y genus Lycaeides ( Lepidoptera : Lycaenidae ) in North America : evidence of recent speciation

  title={Molecular and morphological divergence in the butter ̄ y genus Lycaeides ( Lepidoptera : Lycaenidae ) in North America : evidence of recent speciation},
  author={Arthur M. Shapiro},
Lycaeides idas (Linnaeus) and L. melissa (W. H. Edwards) (Lepidoptera: Lycaenidae) are broadly sympatric in several regions of North America (Fig. 1) and are morphologically distinguishable by qualitative wing pattern differences (Tilden & Smith, 1986), quantitative differences in male genital morphology (Nabokov, 1949; Lane & Weller, 1994) and by ecological differences in habitat speci®city and hostplant associations (Ferris & Brown, 1981; Garth & Tilden, 1986; Scott, 1986; Tilden & Smith… CONTINUE READING
