(From: A Catalogue of the Butterflies of the United States and Canada, Jonathan P. Pelham)

Genus Satyrium Scudder, 1876

Bull. Buffalo Soc. Nat. Sci. 3: 106, no. 8. Type-species: Lycaena fuliginosa W. H. Edwards, 1861, Proc. Acad. Nat. Sci. Philad. 13(6): 160, 164, no. 10, by original designation. The generic synonymy below generally follows Clench (1979), J. Lepid. Soc. 32(4): 277-281, with the caveat that there is disagreement over the rank of several taxa. The group is in need of revision.


Satyrium favonius (J. E. Smith, 1797)

In: Smith & Abbot, Ins. Georgia 1: 27-28, pl. 14, figs. ♂ D, ♀ D, ♀ V, larva, pupa.

Original Combination: Papilio Favonius

Type Locality: “Georgia” implied from the notes to John Abbot’s original drawing.

Types: Described, at least in part, from a John Abbot drawing. The specimens upon which this drawing was based are probably lost.


Satyrium favonius ontario (W. H. Edwards, 1868)

Trans. Am. Entomol. Soc. 2(2): 209-210; figured by W. H. Edwards (1869), Butts. N. Am. [1](4): pl. Thecla 2, figs. 1 ♂ D, 2 ♂ V (holotype).

Original Combination: Thecla Ontario

Type Locality: “Port Stanley, Ontario”

Types: Holotype in CNC; figured by F. Brown (1970), Trans. Am. Entomol. Soc. 96(1): fig. 23 ♂ D&V.

Robbins (1994), Am. Butts. 2(3): 29-30, determined that ontario and favonius are conspecific.
