Synonyms and other taxonomic changes
Codatractus valeriana (Plötz, 1881)
Eudamus valeriana Plötz, 1881
Thorybes mysie Dyar, 1904
Explanation of Names
Mielke & Warren (2004) determined that Thorybes mysie Dyar, 1904 is a junior synonym of Codatractus valeriana. See Print References below.
This species was listed in the 1983 Hodges Checklist as Codatractus valerianus. The original combination was Eudamus valeriana. ICZN code 34.2.1 states "If a species-group name is a noun in apposition its ending need not agree in gender with the generic name with which it is combined and must not be changed to agree in gender with the generic name [Art. 31.2.1]." Mielke & Warren (2004) list this as Codatractus valeriana. Perhaps code 34.2.1 applies here.
Male is without a costal fold.
Underside brown with brown marginal crescents and a pale submarginal band.
In the U.S., southern Arizona near the Mexican border.
Open woodland, drainage areas
Adults fly in late July and early August.
Caterpillars: Legumes, including smoothpod hairypea (Tephrosia leiocarpa)
Adults: Flower nectar; will also sip mud
Adults in July and August; caterpillars overwinter.
Primarily a Mexican species, it is rare and local in the U.S.
Adults are active both during the day and at twilight (semi-crepuscular).(1)
