Cydosia aurivitta Grote & Robinson, 1868
Phylogenetic sequence #
Lafontaine & Schmidt (2010) listed three species of the genus Cydosia
in America north of Mexico. (1)
Extremely sexually dimorphic forewing pattern. Rare, totally blue-black examples exist. (3)
The above note is apparently erroneous. All forms are found in both sexes:
• Form aurivitta has black forewings and broad reddish-orange transverse bands.
• Form imitella, described as a species referring to specimens from western Texas misidentified as nobilitella (Cramer, 1780) and separate from aurivitta, is similar to the latter but with white spots within the black spaces.
• Cydosia majuscula
(Edwards, 1881), raised from synonymy of aurivitta
in Lafontaine & Schmidt (2015) (4)
, refers to the former extreme black form.
Heppner (2003) reported the host was unknown. (6)
also reaches the U.S. in Florida (7)
