Identification
Distinguished from other hairstreaks by early season (March–May in most of range). Combination of small size, blue iridescent upperwing, and single thin hindwing tail separates it from Satyrium and other Theclinae . pattern of fine gray striations with orange marginal spots differs from spring azure (Celastrina ladon), which lacks tail and has more uniform underside.

Appearance
Small with wingspan 21–24 mm. wing surfaces are dark with iridescent blue scaling. surfaces display characteristic pattern with thin, hair-like tail projection on hindwing. Underside marked with fine striations and small dark spots.
Habitat
Deciduous and mixed woodlands, particularly those containing American beech. Occupies mature forest with closed and shaded understory conditions.
Distribution
Eastern Canada and eastern United States. Documented from Ontario and Quebec south through New England, mid-Atlantic states, and Appalachian region to northern Georgia.
Seasonality
active early spring, typically March through May depending on latitude. Single brooded; period coincides with American beech flowering.
Diet
Larvae feed on leaves and fruits of American beech (Fagus grandifolia). Possible secondary use of beaked hazelnut (Corylus cornuta) reported but requires confirmation. feeding habits not documented in sources.
Host Associations

Taxonomic History
Originally described as Thecla laeta by Edwards in 1862; later transferred to Erora.
Conservation Status
Not formally assessed; appears secure within core range but potentially vulnerable to loss of mature beech-dominated forests.
