Synonyms and other taxonomic changes
First described in 1852 by Achille Guénée as Acronycta lepusculina
Acronicta lepusculina
Explanation of Names
From Latin lepusculus- "little hare". The original description compares it to Acronicta leporina, whose name is itself derived from lepus- "hare"
Numbers
uncommon but very widely distributed
Size
wingspan 40-50 mm
Identification
forewing whitish; lines faint except for 3 black blotches representing tips of lines at costa; black basal dash present; usually no orbicular spot
hindwing white
"Although vulpina is usually paler, lepusculina is very variable and Midwestern ones can be nearly white. Vulpina has the PM line more offset towards the wing base and usually has an orbicular spot that is mostly absent in lepusculina...FW shape is more acute in lepusculina." Second comment: "The dark patch in the postmedial area near the anal margin is more offset towards the wing base in vulpina compared to lepusculina, where the whole PM line is more even." - Chris Schmidt
