Archon apollinaris
A smaller Apollo with a wingspan of 50-55 mm, once considered a subspecies of the false but with notably darker markings in the forewings of males and other subtle differences. The little false lives mainly in the eastern part of the country, in vineyards, pastures, woodland, and stony mountainsides. Host plants are represented by birthworts (Aristolochia spp.). This butterfly flies March through July, and is considered near threatened.
