Synonyms: Hodges #4364.
Dusky Azure (Celastrina nigra) is unfortunately considered to be extirpated from Maryland. This species is found in rich deciduous forest in the Appalachians and portions of the midwest, where its host plant, Goat's Beard, may be found. Historically, the species was active in Maryland from mid-April into early May (Butterflies of Maryland: A Biological Summary and Checklist by Lynn Davidson & Richard Smith).
This species is sister to Spring Azure (Celastrina ladon), and like its close relative, the males lack androconia scales on the wings. The males are very distinctive because they are a solid dark gray above, without the normal pale blue coloration of most of the other azure species.
Host plant is Goat's Beard (Aruncus dioicus).
