Wing span: 40mm
Flight time: July
Description. FW like gracilis, but with more contrasting whitish shadings, particularly between pm and st lines; blackish shading along inner margin always present, and usually heavy; prominent black spot between am line and subreniform. HW black, with white apex and blackish fringe. Underside blackish, with only a broad pm band on FW, and apex of both FW and HW contrast-ingly white (fig. 2.4A). 40-50 mm. H 32:3 (as tristis). B & Mc l: 18.
Similar species. The smallest black-winged Catocala. Prominently marked FW, particularly blackish inner margin, easily distinguishes andromedae from miranda and judith. C. louiseae, with similar FW, has yellow and black-banded HW.
Range. Southern Canada (Ontario, Quebec), Maine to Florida (rare) and west throughout area.
Status. Uncommon to common, but somewhat sporadiC. Apparently this species, like others of the Vaccinium feeders, is more common toward the coast than inland.
Larval foodplants. Blueberries (Vaccinium) and possibly Bog Rosemary (Andromeda). Reared on Low Blueberry (V. pennsylvanicum) (TDS).
Notes. Resting habits of moth essentially identical to gracilis.
