Identification of Phyciodes diminutor, P. cocyta, and P. tharos in northeastern U.S. (Nymphalidae)
This issue of Papilio (New Series) consists of three studies on the identification of the closely-related species Phyciodes diminutor diminutor Scott, P. cocyta selenis (W. Kirby)and P. tharos tharos (Drury), from Vermont, Ohio, and Michigan (studies labeled A, B, and C below). Identification problems have hindered the study of these butterflies in the northeastern U.S., and misidentifications have even occurred in recent DNA studies. Difficulties in distinguishing diminutor & selenis, and their status, are discussed. Vermont contains all three taxa in this group. P. tharos has two generations ...
