Depressaria Haworth is a large Holarctic genus with about 100 described species, 24 of which are North American. Known North American Depressaria are Asteraceae and Apiaceae feeders. Host-plant usage is commonly studied in this group; however, no modern phylogeny exists for species of Depressaria. Here we present a morphological analysis using parsimony to investigate species level relationships for North American Depressaria and make conclusions regarding host-plant usage within Asteraceae and Apiaceae.


Species 1: Lepidoptera Elachistidae Depressaria
Keywords: parsimony, morphology
